Initial commit of adding `with()` support to `\Spot\Query`.
Remove un-needed debugging variable.
Adding associations and tests for HasManyThrough and with()
Adding tests and data for HasOne and with().  Involved some tweaking of how HasOne works (it no longer executes in toQuery, but waits until execute() is called on the query).  This _may_ break code that worked around the pre-existing limitation.
Forgot to add Entity_Author to list of tables to migrate.
Fix getting only public properties in PHP 5.4
Merge pull request #45 from vlucas/adding_with
