Updated Permissions Syntax

I left the instances in the permissions module alone since you said you'll be deleting that. 

I wasn't sure how to deal with sub-permissions. 
Ex: https://github.com/swilla/pyrocms/blob/d2bd31bc5daf8f18e99e0d147b954f13e1ecfaa2/system/cms/core/WYSIWYG_Controller.php#L24
Once I know what we are doing with sub-permissions I can finish the rest of these. 

Are we still going to use ```role_or_die()```?
