Based on the copy, move, delete and trash actions provided by the VFS layer, we
need a simple dialog, that display status about the operation and provide the
user with the ability to cancel an operation. 

The dialog class must be able to completely hide the VFS action layer, so that
high-level code simply creates a new dialog and tells it what to do, and the
dialog afterwards handles the communication with the VFS action layer (and
thereby the action thread).
