Mockup: richtexteditor.html

extension/Documentation/_make/conf.py: bumped versiont to 0.4

AbstractException.php: Error messages are no 'htmlspecialchars()' encoded. Error output don't break the formatting anymore.

1) '{{id:R0}}' now gives the correct record id, even on records which are 'new' (id is 0 at time of save) - '{{id:R0}}' can be used 'fileDestination' to build pathFilename.
2) Fixed problem with non existing uploads: in the past a sip has been saved instead of an empty string in the current record.
3) Fixed problem with a) choosing an upload file, b) deleting them immediately and c) pressing 'save'. Non existing temporary uploaded file has been tried to move to final destination.

Documentation/UsersManual: FormElement 'File' update
AbstractBuildForm.php: Extend upload structure with EXISTING_PATH_FILE_NAME.
QuickFormQuery.php: 'late save' of uploads implemented.
Save.php: upload columns are not saved during the first save - instead they are saved later.

QfqController.php: E_NOTICE Errors are by default not catched by T3. For QFQ E_NOTICE will throw exceptions from now on
report/Log.php: unused variables commented out.
report/Variables.php: more detailed isset check.
AbstractBuildForm.php: rendering of 'subrecord delete links' broken if column 'id' is missing. Code, which switches from 'id' to '_id' have been already prepared, but was not completely implemented. Exception if neither 'id' nor '_id' exist in subrecord query.

During save of a record, if column 'modifed' and/or ' created' exist, set them.

Session.php: save feUserGroup through init auf session.
Store.php: During API access restore feUserGroup from SESSION

UsersManual/indes.rst: Desription for subrecord updated.
Sip.php: code cleaned up. Static SIP defined.
AbstractBuildForm.php: Column 'link' implemented.

AbstractBuildForm.php: Column with a specific 'title' starting with '_... ' has not been surpressed. Fixed.

AbstractBuildForm.php: Columns with a name starting with '_... ' has not been surpressed. Fixed. Icons path adjusted.

SIP invalid: it seems that again more SIPs become invalid without known reason. Recoded Store, not to use Session Class - instead $_SESSION is used direct.
Session.php: exception commented
Store.php: recode accessing $_SESSION.

#2046: Dynamic Update mit {{feUser:T0}} Feld - fixed. Background: T3 environment not available during dynamicUpdate (called by AJAX through API). Restore feUser and feUserUid from Session. Not good, but better than nothing. Still missing: the rest of STORE_TYPO3
Session.php: extend checkFeUserUid() to save feUser as well as feUserUid. Fixed error that getSession() in phpDoc stated it returned class Store - correct is class Session.
Store.php: fillStoreTypo3() now respects that if there is no  T3 environment, restore at least feUser and feUserUid.

QuickFormQuery.php: missing 'r' in forms forces no longer an exception, instead r=0 is the default. This is usefull in report for 'new' links to forms (it's not necessary to specify r=0 in '_pagen') as well as on record definition `form=person`: `r=0` is not needed anymore.

Support.php: Constant for double curly braces redefined from '#&@[[@_#', '#&@]]@_#' to '#/+open+/#', '#/+close+/#' - it's more secure not to use '[' or ']' for the substitution string, cause square braces are now allowed as nesting chars.
