Support Auto-Discovery

Leaving glocal scopes to be applied by Eloquent

Closes #245 and finally fixes #281
  newQuery() is used to both create a Builder and apply scopes. This was being
overridden so we could use our own Builder, but it brings more tasks inside
the same overridden method. Thus, we now override newQueryWithoutScopes()
that is indeed the main builder-instantiator, and leave scopes for Eloquent.
