Starting on the server, proper

Should work. Doesn't. Don't know why. Good times.
Alright, it kind of works.

The server, as it turns out, is completely non-resiliant against bad
data. I should figure that bit out...
Dependencies in gemspec
Updated logging

Just wanted to get some basic logging in there. It's not perfect, but
it's better than it was.
Simple client command, register.
Bug fixes for command-line client.

Seems to be working, now.
Updated README

I was thinking that it might be nice to not have to have a heartbeat
thing set up. I don't know if that's a good idea, but in testing,
anyway, it would be helpful.
Updated docs in command-line client.

I realized that the options were off, so I went ahead and updated them..
:)
