Suggestion: Enable & Disable All

I think making a enable & disable button next to the 'Remove (role)' button would help a lot of people enable all the role permissions quickly or disable them quickly. I know this may not be very useful to many people as most people just enable a few important permissions for roles & then leave the rest. However, some people like to have their roles tidy & professional. This is why I think adding this feature would help alot of people out when creating roles & changing the permissions quickly to suit their needs.
