TinyMCE integration: TODO

* make java usecase handler generic and share with other editors
* when done, move these generic usecases into the editors module
* fix wysiwyg: some of the css styles are not properly passed to the editor
content (font-size and font-family)
* add onunload handler to avoid data loss if the user accidentally clicks
on a link or closes the window (confirmation dialog like bxe) - done by
jragaller (patch in bugzilla), needs to be made generic
* allow multiple resource types to be edited with different valid_elements
settings.
* allow multiple editable areas.
