start gemspec

This project still needs the lib structure set-up, tests, CHANGELOG.md,
etc...

Fixes #1.

Not sure if I should include more authors or not either!

We need a version.rb as well.

Should the directory in lib where server.rb lives be called 'resque' or 'resque-web'?  Maybe 'resque' could preserve some capability with existing installations.

I'm interested in giving this project some :heart: , as I'm going to be using the resque web interface for the foreseeable future! Unless a better web interface rolls along...
