Manual.rst: describe how to activate 'report' syntax.
Support.php: implement 'unWrapTag()'
Report: Code reformat
FillStoreForm.php: remove unwanted '<p>' tag around content if TinyMCE is used, before saving the content
AbstractBuildForm.php: new processReportSyntax().
formEditor.sql: Change FormElement Editor column 'note' from Editor (TinyMCE) to ordinary TextArea. This was necessary cause TinyMCE is based on HTML and linebreaks are completely replaced by <br>. It's difficult to support both, HTML and plain text at the same time.
