Bulk remove roles

Hi all. I threw together a component that will let you, theoretically, remove a role from multiple users at the same time.

Caveats:

1. It's not pretty
2. It doesn't catch all (user) errors
3. It's not localized
4. It'll show a green confirmation, even if a user doesn't have the role (Sorry, no idea how to catch that without looping through all roles of every user; and I don't think all those extra api calls are necessary for this excercise.)
5. In the first bit of javascript I'm unbinding "native" form submissions, because, for some reason, Lithium has a baked-in form submission protocol that hinders the custom form code from submitting.

Instructions:

• Enter a role
• enter users, separated by commas. E.g. user1,user2,user3
  I recommend not adding too many at the same time. It makes an api call for every user obviously
• Submit

Good luck.
