Add a GCancellable to EActivity.
EActivity now uses a GCancellable to manage cancellations, instead of having its own redundant cancellation API. API changes are as follows: + e_activity_get_cancellable() + e_activity_set_cancellable() - e_activity_cancel() - e_activity_is_cancelled() - e_activity_get_allow_cancel() - e_activity_set_allow_cancel() EActivity's "cancelled" signal remains, but only as a repeater for GCancellable::cancelled signals. It should not be emitted directly. The presence of a GCancellable implies that cancellation is allowed. EActivity does not create its own default GCancellable, it has to be given one. If a CamelOperation (cast as a GCancellable) is given, EActivity will configure itself to listen for status updates from the CamelOperation and propagate the information to its own "primary-text" and "percent" properties. These changes allowed me to start cleaning up some of the incredibly convoluted logic in mail-mt.c -- in particular, mail_operation_status() is completely gone now. mail-mt.c is still in a transitional state -- much more significant changes coming soon.
