core: migrate the main client to ServiceBot (#216)

- irc.spawnMain is dropped. Clients are now spawned in the endburst loop, after protocol negotiation completes. This allows PyLink to spawn clients with hideoper, etc., closing #194.
- utils.add_cmd and irc.callCommand are now just wrappers around world.services['pylink'].add_cmd and call_cmd respectively.
- coreplugin registers the main client while it is loaded up, before any commands are added.
