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 `$_GET['mime']`.
Fixes itself.
`$this->info` can very well contain an empty array or possibly other values. This means that when this code path is called a PHP Fatal error might get thrown which is not what we want.
* options for timeout in seconds and if it contains HTML
* if timeout is 0 it will show the message permanently
* removes the notification after a given (default: 5 seconds) timeframe
* based on work by @brantje
* provide JS unit tests for notifications
Currently if a user does not replace the .htaccess file with the new update this can lead to serious problems in case Apache is used as webserver.
This commit adds the version to the .htaccess file and the update routine fails in case not the newest version is specified in there. This obviously means that every release has to update the version specified in .htaccess as well. But I see no better solution for it.

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.
