Title: Provide a generic rake task (deploy:build) to make changes before slug compilation.

I've had a need for hooking into the slug compilation process before the slug is actually compiled to generate data. Before the automatic running of `rake assets:precompile` was added, there was not an easy way to do this.

Rather than using non-asset related code in the `assets:precompile` task I think it makes sense to have a generic `deploy:build` task that people can use as a hook for doing whatever it is they need to do before compilation.

Thoughts?
