Add e_lookup_action() and e_lookup_action_group() to e-util, so

I don't have to keep writing the algorithm over and over again.

Add EFileActivity, which provides a GCancellable for GIO operations.
Cancelling the activity cancels the GIO operation, and vice versa.
Also provides a handy GFileProgressCallback function which updates
the activity's "percent" property.
