ProfileName validations

1. The ProfileName field now has a validator. This validator makes sure that no duplicate names can be selected (it also checks for whitespace).
2. Captions for the tabs now update correctly after changing the profile names, the default profile, or when adding a new profile.
3. Upon creation of a new profile, the new profile's "Name" field is auto-populated with the full name stored in Accounts. This stops the "Error validating form" notification from popping up each time a new profile is created.
