* add keybase to bridgemap

* send to right channel, try to figure out received msgs

* add account and userid

* i am a Dam Fool

* Fix formatting for messages, handle /me

* update vendors, ran golint and goimports

* move handlers to handlers.go, clean up unused config options

* add sample config, fix inconsistent remote nick handling

* Update readme with keybase links

* Resolve fixmie errors
