Rewrite generate to use Thor rather than Rubigen

Rubigen was minimally maintained, and Thor is better maintained as well
as being the generator framework used by Rails since 3.0. This should
also fix generating gateways when using newer versions of ActiveSupport,
since Thor has no dependency on ActiveSupport at all (see #453).

Closes #453, #502.
