[TYPO3-core] RFC: #9109: Enable feature in element browser in rte like in normal one

[Stanislas Rolland]

Hi Steffen,

Two comments after testing with trunk.

The filemounts listed on the option are correctly added to the 
filemounts to which the user already has access to. However, the 
pagemounts listed on the option replace all accessible pagemounts, they 
are not additional, so that the pagemouts to which the user has 
otherwise access do not appear in the pagetree.

In the case of image insertion, if the file tree is opened inside an 
additional filemount, the file upload and folder creation forms are 
available, but produce an access right error if used, which is not very 
friendly.

Regards,
Stanislas
