added skeleton files created for a new engine, should fail horribly but we need to check that the mounted rails_admin engine will still work in an engine in an app
fixed loading of rails_admin in engine
moved migrations: http://pivotallabs.com/leave-your-migrations-in-your-rails-engines/
moved cancan into engine
making sure the customizations to rails_admin will be loaded first in the main app
use a more flexible app name, updated Gemfile.lock
