We discourage checking in artifacts (e.g., minified JS) into source control because it defeats the purpose in a lot of ways. Currently there is no support for custom build/test steps but the builds that are done for Java apps are done using Jenkins so you can imagine that in the fullness of time anything Jenkins supports would also be supported as a pre-deploy step. I don't have any specific details though, as my work has been focused on the GitHub integration.
