Move 'in-bots' logic to getin_request() (#35)

This will give the bot a $in_bots/$opped_bots chance of responding to
the request for invite. This cuts down the bandwidth as bots no longer
need to brute force ask their way into a channel. They can just
broadcast the request and eligible bots will respond.
