Add \Gasoline\Model\Widget
Some small UI changes to admin/modules/list
Some changes to the gasoline base controllers

Mainly introduces static::restrict() as a wrapper for checking for logged in users and redirecting the otherwise. Can now be used in other controllers like any \Controller\Widget that requires logged in state
Add some 'always_load' to gasoline config config

Now they're always loaded no matter what APPPATH.config/config.php says
Update gasoline config/app to set some theme defaults

This is going to be used to set the theme to be used more dynamically and depending on the URI (for later this will allow each theme to have its own error pages)
