Split up gem

[kristianhellquist]

As a developer I would like to include the requester in my rails project without the gems that are used by the server and runner So my development setup gets less gem dependencies

:-)

Yes this would be good. It would make release more complicated though, but probably worth it.

Probably a meta package and a package for each target (don't need the sinatra dep, etc. for a runner). testbot -> testbot-requester testbot-runner testbot-server
