configure travis to setup the db first
Updating the schema with email change seems wise.
Ensure that we don't have database issues by dropping, creating and migrating the database before running specs on travis.
Add blank seeds file so rake db:setup works
Hidden has already been added to forem_forums, no need for this other migration
merge conflict
[specs] Add hidden back to topics in dummy app so specs will pass.....
Remove all references to current_user, replacing them with forem_user.  Apps can expose a forem_user controller method to specify what should be used to reference the logged in user.
teach posts, topics, views to be more liberal with what a user is.
Bump Rails version in Gemfile.lock
Alter travis.yml to actually run the tests
Fixed admin dealies
Added default value of false to locked topics migration. This prevents needing to use !!topic.locked to coerce it from nil into true or false.
