Rolling back the features upgrade from #61

## Ready State No
This patch rolls back the features upgrade from #61 

Alternatively this could also just be done using git revert, but merging this will keep the git history intact so we can see what happened.

The reason this needs to happen is that the features module 2.0 release breaks the installkit due to a few changes in it. I haven't yet determined the fix for those changes so in the mean time we need to just roll the features module back to keep the build working. I think it may be prudent to go ahead and roll this back for the moment until a fix is determined so that `site-install` can work in the meantime.

## Testing the current code
- Run a drupal make, everything should build correctly
- Then run site-install. At some point you will get PDO Exceptions (I had them related to the RDF module)
