Feature #4720 - Implemented select-list with dbIndexList as FE.parameter option. Works, but is unflexible. Looking for a better solution.

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.

Feature 5425 / thumbnail: rewrite - secure thumbnails are now rendered on first access, not when 'AS _thumbnail' is called.

#5367 / Error Report: 'full level' missing, content too much escaped: Fixed too much escaping. Form / FormElement Links in error messages now with BS Buttons.

New FE.parameter 'inputType'. Can optional be given by webmaster. Additional, the 'type="number"' will be automatically set, if the column is of type 'int' or if 'min' and 'max' is numerically.

#5022 / Variable violates sanatize class: 'msg' instead of empty string - new identifier "!!<sanitize class>!!"

Add new class 'qfq-table-100' - 100% width, with auto width per column. FE.subrecord changed to  'qfq-table-100'. Add new class qfq-full-width-left: especially for buttons to become full width.

Feature 5295: Upload: check if given QFQ 'maxFileSize' is higher than php.in post_max_size, upload_max_filesize

Form / Upload: new option 'downloadButton' - if given renders a download button instead of showing the pathFileName
Support.php: new isEnabled()

HelperFormElement.php: AppendFormElementNameImageCut()
Support.php: Force Sanatize Class fuer FE.type=imageCut.
AbstractBuildForm.php: Add source filename to SIP
QuickFormQuery.php: Call $save->processAllImageCutFE();
Save.php: processAllImageCutFE(), extractImageDataReplaceFile()

DatabaseUpdateData.php: extend FormElement.type to 'imageCut'.
Support.php: extend joinPath() to join path parts optionally without using file as absolute path. Implement unit tests.
Download.php: doc
AbstractBuildForm.php: implement FE,typ=imageCut
formEditor.sql: update FE with new element imageCut.

#5133 / sendmail: subject and body html entity decode: Introduce options for 'subject' and 'body' to switch on/off HTML encoding / decoding
