Made bootstrap controller summary errors more plain/consistent and thoroughly reported them
Added support for additional properties on UserProfiles during SimpleMembershipProvider registration etc.

Modified AccountsControllerBase to require an TUserProfileViewModel type parameter which it will instantiate inside wrapper
 registration classes that are sent to the user's views so that a user can insert the required information and it will be mapped to the new UserProfile
entity upon completion of registration.
Removed unnecessary virtual keyword in view model properties
