Empathy still doesn't show us as connected. I think we need to add the
Requests and Contacts interfaces (which we're advertising as a minimal
requirement, but not implementing) before it will.
We also introduce a sleep() to "fix" a race condition where empathy
tries to contact the connection bus name before the thread has gotten
around to starting it. That really needs fixing better, but for now
I'm focused on basic functionality.
Without this, telepathy-glib/empathy doesn't believe the protocol is
bonafide (i.e., implementing TP_PROTOCOL_FEATURE_CORE). Adding a dummy
gets empathy to display the protocol without needing to be patched \o/.
