apply_for_role 8.x-1.0-alpha2

Removed all of the old code that was in there just for reference. Shouldn't have been in there at all. Can be referenced by viewing D7 branch.

Fixed strict warnings on administer applications page. I was passing a value returned from an object instead of a variable, and since the function takes the variable by reference, it complains since it can't alter the param passed since it's not stored as a variable.

Fixed emailing administrators on application submission. This was actually broken entirely, and was overlooked. Now functions so as users can still apply, and emails are sent either to superadmin or comma separated list of emails.
