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

Feature #6314 - HTML Mode & sendMailSubjectHtmlEntity for Forms. Also fixed some issues with Documentation and implementation.

HelperFormElement.php, SessionCookie.php, Html2Pdf.php, Store.php, Constants.php: migrate to camel case on configuration variables.

AbstractBuildForm.php: Add source filename to SIP
QuickFormQuery.php: Call $save->processAllImageCutFE();
Save.php: processAllImageCutFE(), extractImageDataReplaceFile()

Bug #5031 / Missing details in DbException: New definition of SYSTEM_SHOW_DEBUG_INFO: even after config.qfq.ini is parsed and SIP Infos has been read - if there is no BE User logged in, the value stays on 'auto' (earlier it has been replaced to 'no'). Staying on 'auto' keeps the information that replacing is still open and not replaced means 'no'-BE User logged in.

* Broken Redirect after Save - fixed
* Broken same HTML ID for FE copies in a template group. - fixed

#4386 Fuer GRC: Optional Info Button bei 'input' wie bei 'textarea' - EXTRA_BUTTON_INFO_POSITION=below

HelperFormElement.php: moved function 'explodeTemplateGroupElements()' to 'QuickFormQuery.php'
Database.php: remove call to explodeTemplateGroupElements() - not necessary at that place.
