[TYPO3-core] RFC: #7028: Implement CSH for flexforms

[Dmitry Dulepov [typo3]]

Hi!

This is SVN patch request.

BT reference: http://bugs.typo3.org/view.php?id=7028

Brunch: trunk

Problem: it is impossible to use CSH in flexforms.

Solution: implement it in t3lib_flexforms and view_help.php. Attached: patch, screenshot and test extension. To test the patch, install extension, add it to page and look at its configuration. All CSH features are supported including images. CSH file should be created normally and reference to it added to flexform xml (see another screenshot).

Notes:
- this patch does not take RFC 6995 into account but it can be easily adjusted of RFC 6995 is approved
- information for CSH for tables is created inside sysext/lang and can be included into common system-wide index. This would be a big overhead for flexform CSH because requires parsing all possible flexform xmls. I did not implement theat (I do not feel it is necessary). So CSH for flexforms is available only when flexform is displayed.
