Summary of Changes

At the moment, the filter settings for HTML tags and attributes in the Tiny MCE are completly independent from the Joomla! settings (=> Global Configuration). So it's possible, that elements are allowed in the Tiny MCE but are forbidden in the Joomla! filter or vice versa.
With this patch it's possible to ignore the Tiny MCE settings and use the Joomla! settings to have the exact same filter rules and no variance. Special advantage: with this new function it's possible to define the rules for each user group!

Testing Instructions

1. You need at least one user who is not super user
2. In global configuration define textfilter for the usergroup the user belongs to, as for example set White list and allow the tag iframe and the attribute background.

3. Login as this user and write a new article which contains an iframe. Save the article and the iframe disappears if it is denied in TinyMCE.

4. Apply the patch

5. In the TinyMCE Plugin set the new Param "use Joomla textfilters" to on.
6. Login again as the user and write a new article containig an iframe and a style baykground
7. For this user, iframe and background will remain
8. Now play around and test some combinations, allowing and denying different tags or attributes to different user groups
