[chef] What are the available methods does deploy_revision have to check the source repo versions?

Hi Chefellas!

I've deployed a rails 3 app using `deploy_revision` resource with asset compilation is done inside the `before_restart` block and it works fine.

Since it takes too long and though any assets is not changed, it will still do the precompilation.

  before_restart do

    bash "asset_precompile" do

      cwd current_release

      user app[:owner]

      group app[:group]

      code %{

        export RAILS_ENV=#{rails_env}

        bundle exec rake assets:precompile --trace

      }

      action :run

    end

  end

There are several work arounds in capistrano. One of which is https://github.com/capistrano/capistrano/pull/174/files#L1L40

Does the deploy_revision have the following kind of methods which capistrano has?

e.g. `source`, `previous_revision`

So that I could make the asset compilation conditional.
