Fixes #7620. Label align left/center/right. Defined by config/form/formelement. FormEditor slightly redesigned.

Refactor: Manual.rst update config variables (reorder), add 'qfqLog'. Support.php: formSubmitLog hardcoded to fileadmin/protected/log. DOCUMENTATION_QFQ > SYSTEM_DOCUMENTATION_QFQ. Remove config var 'logDir'.

Config.qfq: central defaults for DATA_MATH, DATA_ERROR

HelperFormElement.php, SessionCookie.php, Html2Pdf.php, Store.php, Constants.php: migrate to camel case on configuration variables.
Config.php: readConfig() reads now config.qfq.ini and T3 LocalConfiguration.php.

Link.php: SIP Links get automatically parameter '__dbIndexData'
Report.php: can select DB via 'dbIndex' directive (global)
AbstractBuildForm.php: dbIndexData now based on setting in Form (before on config.qfq.ini)
formEditor.sql: FormEditor update on Form 'form' and 'formElements'

Implemeted two new STORE_SYSTEM variables: '_dbNameData' and '_dbNameQfq' - those will be automatically filled qfq during instantiation QuickFormQuery(). They can be used in Report to easily access the needed DB.

Store.php, AbstractBuildForm.php, QuickFormQuery.php, Save.php: change signature of appendToStore() to be eqal to setStore().
Unittests for appendToStore.php

BuildFormBootstrap.php: make buildPillNavigation dynamicUpdate aware.
QuickFormQuery.php: Fix problem with missing HTML_ID in FE.

phpUnitTests: fixed some defintions of string/int

DatabaseUpdateData.php: removed the DB update from last commit - not necessary.
Config.php: New default 'm'
Evaluate.php: Respect EscapeTypeDefault in form definition.
QuickFormQuery.php: Replace 'EscapeTypeDefault' in form defintion very early.

Manual.rst: add documentation for record locking
DatabaseUpdateData.php: Add new column 'dirtyMode'
Dirty.php, Config.php, formEditor.sql: remove dirtyMode=readonly. Rename 'timeout' to 'exclusive' and 'overwrite' to 'advisory'.

First version for save - not working now.
Manual.rst: document config var SYSTEM_DIRTY_RECORD_TIMEOUT_SECONDS.
QuickFormQuery.php, Dirty.php: extend to support QFQ/save().
Client.php: fixed broken PHP Unit test
Config.php: set default for dirtyRecordTimeout.
BuildFormBootstrap.php: No dirtyUrl if dirtyMode=none.
formEditor.sql: extend definition to Form.dirtyMode, new table 'Dirty'
Fixed several unit tests for new tables.

QFQ complains that the given SIP parameter is already defined. Problem is the pre filling of Store SIP, which normally happens only during form load. But the new 'saving a new record (r=0) and redirecting the browser to the same page with the new record id', requires a new SIP. That SIP is calculated before form-load and causes the exception. Fix: defined parameter in a store, which will be redefined with the same value, wont' throw an exception anymore.
Store.php: compare old and new value and only if they differ throw an exception.

unit test fixed.
