Return error when token is empty, undefined, or null.

[michaelckelly]

Currently, a call like:

authy.verify(authyUserId, twoFactorCode, callback);

will return

{ message: 'Requested URL was not found. Please check http://docs.authy.com/ to see the valid URLs',
  success: false,
  errors: { message: 'Requested URL was not found. Please check http://docs.authy.com/ to see the valid URLs' } }

when twoFactorCode is equal to '', null, or undefined.

I think it'd be clearer to callback with a direct error here (in this case, that the token cannot be null/missing) as opposed to returning a more obscure 404 API response.

can you make it return an Error rather than just a String.

+1 to Error objects

@danielbarnes and @evilpacket:

Sure thing - updated to callback an Error object.
