Christian Dywan fa08c4d1f9 Refactor transferbar into MidoriTransferbar 
The transferbar is separated from the browser, albeit it is still
created and filled from within the browser so it is not completely
independent.

The new class now keeps a list of TransferInfo items to keep track
of transfers and queries the status from the download object.

Destroying a button belonging to a transfer is connected to
removing it from the list and cleaning up the info structure. Also
the Clear button is updated from the destroy handler.
