[phorward]

The resources/ folder in the server is a dump for legacy libraries and files which are mostly unused.

It's true that time must be investigated to find out which of these resources are still in use by the server (the error-template, for example!). Anyway, it is important that thinks like tinymce or a jquery-version from 2013 are removed soon, so this ticket is serves as a reminder.
