Roles

Hi,

Some changes that might make managing roles a bit easier:

Create new role from existing - copies permissions of existing role to a new one.
Reset role to defaults - for Admin and user, an option to reset them to default. Even if it's a rake, that would be fine.
View all permissions - give the option to display all permissions on one page, rather than paginating it. Oh and add the pagination to the bottom of the page. Saves people having to scroll up to get to the next page.
Make 'Full Access' + 'Deselect All' Filter/Groups context sensitive - it's not clear now that when you display a group and then click Full Access, that you're actually applying full access to all groups.

Cheers,

Nick
