Fixed rendering checkboxes: alignment of multicheckboxes was still buggy - multi in vertical and horizontal are ok now. The labels too.
AbstractBuildForm.php, Constants.php: The checkbox is now only wrapped in a <label> element in ALIGN_VERTICAL Mode. This is identical to the radio.

Fixed rendering of ' checkbox'. formelement.parameter['orientation'] removed (replace by formelement.maxLength)
UserManual/index.rst: Doc updated for checkbox/maxlength.
AbstractBuildForm.php, Constants.php: class 'checkbox' and 'checkbox-inline' always rendered. Insert <br> where necessary.

AbstractBuildForm.php: Class 'radio' or 'radio-inline' assigned to each individual radio element. After formelement['maxlength'] elements, a <br> is rendered.

QfqForm.js: support `required` configuration attribute.

Recode: fromelement.mode='readonly' new implemented on client, by using CSS attribute 'disabled'. The HTML atrribute 'readonly' is fine for pure 'input' elements, but does not work sufficient for 'select', 'checkbox', 'radio'. Also, the label (left of input) and note (right of input) are now grayed out if set to 'disable'.
FillStoreForm.php, Save.php: strings replaced by constants. New central function getfeMode() used by getJsonFeMode() and getAttributeFeMode()

Support for `data-hidden` and `data-disabled` attributes, which are used to initially configure form elements.

Formelement.mode='lock': removed, cause it seems that there is no difference to 'readonly'. Inside the code, there is no difference
UserManual/Index.rst: doc updated
FillStoreForm.php, Save.php: same functionality like FE_MODE_READONLY - removed.
formEditor.sql: definition updated

Support.php, FillStore.php, AbstractBuildFrom.php, BuildFormPlain.php, BuildFormTables.php, Constants.php, Save.php, BuildFormPlainTest.php

Form/subrecord: implement special column name '_rowTitle' - shows tooltips over a row of subrecords.

QuickFormQuery.php: changed the defaults for Bootstrap forms again - look nicer on UZH CD Layout.
*.sql: Colorized subrecords for FormElements, ord will automatically computed, work on example forms (not finished)

AbstractBuildForm.php: Das Zeichen fuer Konstanten '#' war doppelt belegt. Es bedeutete auch Kommentar. Kommentare werden vor dem processing entfernt. Neu ist das Konstannten Zeichen '&'.

Bootstrap grip columns are configurable. A default on the form and, if necessary, per formelement. The default is now changed from 2,6,4 to 2,9,1

UsersManual/index.rst: more details to 'Type: subrecord'
AbstracctBuildForm.php: check if there are no subrecords. No subrecors mean: display only the 'new' button. prepareSubrecord() returns now 'true' even if there are no subrecords.

UsersManual/Index.rst: See 'Type: subrecord'. Some hints how to use '_rowClass' to mark rows individual.
AbstractBuildForm.php: implement in buildSubrecord() parsing of column '_rowClass'. Active roll-over by assigning class 'table-hover' to the class.
formEditor.sql: disabled form element records now 'text-muted' displayed.

Report.php, Database.php: triggerReport() supports stat[] with num_rows, affected_rows and insert_id. rowTotal does not contain anymore inserId (last_insert_id) from fired INSERT queries. Instead num_rows or affected_rows are choosen. New: <level>.line.inserId contains the insertId.

Parsing of the bodytext failed for single curly braces inside.
BodyTestParser.php: After cleaning the bodytext all nesting curly braces will be replaced by complex token. stripAndRemoveComment() renamed to trimAndRemoveCommentAndEmptyLine(). process() throws an exception in case of unmatched open curly braces. New encryptNestingDelimeter() / decryptNestingDelimeter(). Remove handling for escaped curly braces in unNest() - this should not be necessary anymore.

Sanitize.php: new sanitize class ALLBUT. New function safeFilename().
Support.php: New function mkDirParent().
Store.php: new system config variable SYSTEM_SITE_PATH.
QuickFormQuery.php: fills STORE_RECORD before saving the current record.
