Do not double decode values

Fixes https://github.com/owncloud/core/issues/11012
remove icon styles from apps.css as they are in icons.css
use same shade of grey for active navigation items and hovering
Remove passing by reference to allow for proper GC

The garbage collector in PHP 5.3.10 does not properly release the file
handle when calling fclose() due to the fact that it is passed by
reference.
This has the side-effect of preventing file locks to be released as well
when the files_locking app is enabled.

This fix removes the useless passing by reference and now the file
handle and file lock are freed properly.

remove bottom: 0 to prevent the menu form overlapping the whole element. This happens if a folder has entries, the menu expands to the very bottom and overlaps all entries and makes them impossible to click

fix input width which was changed likely with the icon PR

use calc because firefox and chrome have different scrollbar widths which causes firefox to push the button into the next row while everything is well in chrome

add normal width for IE8
Add timeout to user and group deletion notification

Added timeout in DeleteHandler to auto-delete after a delay.

Fixed issue where OC.Notification.hide() was called twice in a row when
deleting multiple entries, causing the second notification to disappear.
Fixed issue where "undo" click event handler was registered multiple
times when calling setNotifications() twice.
Added JS unit tests for the DeleteHandler class.

Refix undo users, groups feature

Timeout is now cleared in cancel().

Fixed click handler name for "undo" to be able to work with multiple
DeleteHandler instances (in our case one for users and one for groups)
so that there is no conflict.
