* tinymce is not used anymore, we can delete the cuson CSS file
* mv the plugins_details template to addon_details
* renamed template called from admin panel
* some CSS classes that should be addon where still plugin
* Insert a warning into the generated quattro CSS files
* Seperate blocks in /admin/features.
Its hard to distinguish between blocks of settings in the features page. Its
useful to clearly mark the blocks belonging together.
* Also try to separate items for other themes.
* Make sure separate settings boxes work in all themes.
The aside menu in the admin panel is now handled in one array, which also
holds the submenu items. Also the sections of the menu are now a bit more
structured and separated from each other.
This is a followup on #4266 resizing the fedstat graph in the admin panel
so that it fits alongside the intro text again. Checked also with duepunto,
quattro and vier theme.
