Replace EActivityHandler with a new activity-tracking system that uses

EActivity objects instead of numeric handler IDs.  Create an EActivity,
configure it, and (optionally) connect to its "cancelled" and "completed"
signals.  Then hand it to the shell view via e_shell_view_add_activity().
When finished with the activity, call e_activity_finish() and unref it.
