Allow batch deletion of media.

Browse Source 
It is now possible to batch-delete media in the "media overview" screen.
You can long press to enter multi-select mode. Then a delete button
appears on the menu bar. After pressing delete, you will get a
confirmation, and if the user confirms, the items will delete while a
progres dialog shows.
