Ldap.php: replacement of '?' in LDAP search not processed with MODE_LDAP_PREFETCH - fixed. FE_TYPEAHEAD_LDAP_KEY_PRINTF renamed to FE_TYPEAHEAD_LDAP_ID_PRINTF
AbstractBuildForm.php: copy 'FE_TYPEAHEAD_LDAP_ID_PRINTF' to SIP seems never be done - fixed

#3552 / typeAheadLdapSearchPerToken - webpass kann nicht gleichzeitig nach Vornamen und Nachnamen suchen
Neuen Modus 'typeAheadLdapSearchPerToken' implementiert.
Manual.rst: neues Feature dokumentiert.
Ldap.php: Neue Funktion 'explodePermutSearch()'.

During expanding of templateGroups, existing FE with no meaning for save (like note, subrecord, ...) has been created, filled with empty values and saved. Fixed for FEs with type 'subrecord' and 'note' - needs more investigation to check for further sideeffects.

Action elements, assigned to a container which are not a templategroup, threw an exception. In general, it makes no sense (at the time of writing this) to assign an action element to a pill or fieldset, but it should not throw an exception. Fixed - just ignore such assignment.

Implemented.

Exception: rewrote getting T3 parameter without using Store(). Always report pages.uid, tt_content.uid.
 T3Info.php: new class
 Sip.php: penalty time for broken sip.
 Store.php: moved T3 code to T3Info.php

#3502 / TemplateGroups: Checkboxen werden beim ersten Speichern (insert) nicht geschrieben - ein anschliessendes Update ist ok
Das Problem tritt nur auf bei MultiCheckboxen. Neu werden im Store  STORE_ADDITIONAL_FORM_ELEMENTS (ist bereits frueher, extra fuer Checkboxen, eingefuehrt worden) fuer alle TemplateGroup FEs (type=checkbox) die Fake Elemente angelegt. Dazu wird neu NAME_TG_COPIES in dem FEs gefuellt mit dem 'TG max copies'-Wert.

Manual.rst: update doc how to insert/update/delete non primary templateGroup records.
FormAction.php: removed $templateGroupIndex - solved implicit by defining a LIMIT on 'slaveId' . Implemented '%D' (one below %d). Implemented FE_SQL_HONOR_FORM_ELEMENTS - reduces unecassary SQL queries.
HelperFormElement.php: moved function 'explodeTemplateGroupElements()' to 'QuickFormQuery.php'
Database.php: remove call to explodeTemplateGroupElements() - not necessary at that place.
QuickFormQuery.php: fill STORE_RECORD during Formload - to read templateGroup records very early. Local copy of `getNativeFormElements()`, new `explodeTemplateGroupElements()`

Mode: typeAheadPedantic
TypeAhead.php: Implemented new parameter  TYPEAHEAD_API_PREFETCH.
Ldap.php: add new mode MODE_LDAP_PREFETCH
AbstractBuildForm.php: If FE_TYPEAHEAD_PEDANTIC is specified, add attribute DATA_TYPEAHEAD_PEDANTIC,'true'

Implementation started - code is broken

Neu: Form.parameter.saveButtonActive - if this attribute is set, the save button will be enabled directly on form load.
Manual.rst: update doc
BuildFormBootstrap.php:: Add new attribute to 'form'-tag

Implemented the option to make a form `readonly`. this can be done statically or dynamically via variable (e.g. SIP).

#3447 / Icons das man im FrontEnd direkt das gewaehlte FormElement im Formulareditor bearbeiten kann.

Manual.rst: Updated doc for a) config.qfq.ini: LDAP_1_RDN, LDAP_1_PASSWORD, b) Form.parameter|FormElement.parameter: ldapUseBindCredentials
ErrorHandler.php: removed details - the end user should not too many details.
FormAction.php, Ldap.php, QuickFormQuery.php: implement 'ldapUseBindCredentials'
Ldap.php: set_error_handler() to catch ldap_bind() problems. Always set LDAP_OPT_PROTOCOL_VERSION=3 - this might cause problems with som LDAP Servers - we will see.

#3447 / Icons das man im FrontEnd direkt das gewaehlte FormElement im Formulareditor bearbeiten kann
AbstractBuildForm.php, BuildFormBootstrap.php, BuildFormTable.php: Function createFormEditorUrl extended to accept parameter, to make it more generic (best would be to use the 'Link' class). Build the FormElement Edit symbol as together with debug stack symbols

The new implementation creates empty fake instances of all copies of templateGroup FormElements. Those are empty. Before save, the submitted form values will be expanded with the empty fake templateGroup FormElements and such empty values will be saved.
FormAction.php: Rename constant SQL_FORM_ELEMENT_TEMPLATE_GROUP to SQL_FORM_ELEMENT_TEMPLATE_GROUP_FE_ID - to be more precise.
HelperFormElement.php, Database.php: new function explodeTemplateGroupElements()

AbstractBuildForm.php: Saving 'extra' FE in STORE_SIP has been done with inappropiate FE_NAME. Correct is the pure FE_NAME, without any extension like recordId. Unessary and broken decoding removed.

AbstractBuildForm.php: Load foreign values in templatGroups.

Typeahead (#3369): Parameternames has changed, configuration is possible on the Form and on the FormElement.
typeahead.php: if there is an exception, the message body is sent as regular 'content' for the dropdownbox. At the moment this is the only way to transmit any error messages.
Ldap.php: missing FE_TYPEAHEAD_LDAP_KEY_PRINTF, FE_TYPEAHEAD_LDAP_VALUE_PRINTF will be substituted by the other. If both missing, an exception is thrown.

load.php (#2081): rearrange delivered JSON to fullfill client API.

Index.rst, AbstractBuildForm.php, BuildFormBootstrap.php, Constants.php: split buildRadio() in constructRadioPlain() and constructRadioButton. After several tries to make a base function for both construct variants, CR decided that the code is much more easier to read with to complete separate layout functions.

AbstractBuildForm.php: Notes of input elements as well as the text of a 'Note' FormElement are now wrapped in the class 'qfq-note' - this aligns the text to the label baseline.
