[TYPO3-core] RFC: element browser hook

[Stanislas Rolland]

Hi René,

I finally modified htmlArea RTE to use these new classes. This is a good 
improvement. There are still some functions that I need to overload 
because the rte editor number needs to be forwarded (when there is more 
that one RTE-enabled field on the page).

This is now in CVS HEAD.

In the case of images, I also added integration with the DAM media 
browser. This works better. Hopefully I did not mess things up by 
reusing bparms position 1 and 2 to store the editor number and 
rteConfigParams (also to ensure that these get forwarded).

There are two back path settings that are missing in DAM. I posted those 
in the bugtracker: http://bugs.typo3.org/view.php?id=3370 and 
http://bugs.typo3.org/view.php?id=3371

If you have time, it would be nice if you could review 
sysext/rtehtmlarea/mod4/class.tx_rtehtmlarea_dam_browse_media.php to see 
if there is anything that could be improved or factored back to DAM.

Best regards,
Stanislas
