Incomplete and non coherent account type enum

[dkocher]

The types and wording in AccountType ^1 does not reflect the available plans advertised ^2. This is probably an issue with the API itself ^3 but would at least require updated documentation.

More specifically we need a mapping to the enum types for the following plans from marketing

Enum Type	Plus	Family	Professional	Standard	Advanced
BASIC
PRO
BUSINESS

Thanks for writing this up! I'll ask the team to update the API/SDK to include this more detailed plan information.
