Make EShell a subclass of UniqueApp and handle single-instance negotiation.
When another Evolution process is running:
- Running "evolution" will simply present the existing windows.
- Running "evolution -c <view>" will open a shell window set to <view>.
- Running "evolution <uri>" will open an appropriate window for <uri>.
The second process will then terminate immediately.

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.
