- Updated documentation

- Renamed the 'Type' constants to 'AccountType', and renamed the 'type'
  attribute to 'accounttype' to avoid collision with Object#type.

- Added typecasts to accounttype to fix the is{Admin,Implementor,Creator}?
  methods.

- Changed to_s() to show the account type of the user if they're more than a
  simple user.
