Update authors and mark as v0.0.0
Remove path and versions in Gemfiles for answers gems
Caught a few more namespace errors in tests.
Adding answers-core to gemfile for now.

I thought this should already be loaded but after moving to remote gem
versions of answers I get an error about about core not being loaded.
Oddly this does not occur when you create an app from the remote gem.
Restore capistrano, chef, vagrant, and other misc. bits
Merge branch 'feature/gemify' into feature/196_enginification
