This fixes an issue when renaming files from a flat list view like
"Favorites" or "Shared with you", in which case the path needs to be
present in the response to make sure the data-path attribute is properly
set in the JS side.
To make it possible for the web UI to correctly display the tag/favorite
information after a rename, this information is now returned in the
rename response
Whenever tags are updated, they need to be updated in the file list's
file info array as well.
This commit also adds unit tests and makes sure that whichever tags are
sent back by the server after update are used when updating
attributes/fileinfo.
Make it possible to drop files below the table even if the table is
smaller than the window height.
Added a check to make sure upload is not triggered on invisible lists.
We already use `.text()` here which automatically properly encodes the string. Thus the string will be double-encoded and look ugly. (i.e. when you search for ">" you will see "No results found for >")
Fixes itself.
Otherwise a fatal PHP error is thrown since the filesystem is not setup:
```

Furthermore this adds the CSRF check as a nice-to-have addition, the requests accessing this are done via the jQuery AJAX methods and thus the header is automatically added to all requests already.
Otherwise when the file without any specified mimetype was accessed the error log was flooded with entries such as "Undefined index: mime", there can be multiple issues found about this in the forum and our bugtracker.
To test this access `/index.php/apps/files/ajax/mimeicon.php` with and without `$_GET['mime']`.
Fixes itself.
Whenever an external storage mount point is shared directly, its path is
empty which causes a leading slash to appear in the source path.
This fix removes the bogus leading slash in such situation.
