Fix for #288 (Dashboard Re-skin: System and Settings > Permissions and Access > User Permissions)

This fixes the graphical side of things.
I found some issues with the Add Access Entity interface however. 

Steps to reproduce: 
1. Select one of the permissions
2. Click Add
3. Select 'User' from the select drop down http://puu.sh/9H2mR/1f8124e78e.png
4. Error

I tried to do some digging but got nowhere.
