OS-ACE Integration

First swing at getting OS-ACE involved with spinning up sites. I've tested this as far as pulling down Turnip, generating the install profile, spinning up the theme, installing the site, logging in, choosing the newly generated theme as default. There are no errors, the site loads normally, and it looks like we have the base css from alphecca/bedrock. From that point it looks like we could probably use some default panels config cause there's nothing on the page except for a not found message and a link.

In any case, further testing in other peeps' environments would probably be good to make sure nothing is awry in the basic workflow of generating a Turnip site utilizing OS-ACE. Also, i didn't add the Grunt integration to this version of things, as I'm not sure who besides me wants to use it.

So, at this point it's really just evaluating whether or not Turnip still works as expected with the integration, and deciding if we need more initial config to make it useful. The Grunt integration would also be another thing to decide on as well.

Please test.
