Get all accounts from all locations

[Richard Barnes]

Since the create booking endpoint requires the account number of the user, I must find the account number.

However, the only way I can think of to do this for an arbitrary user is to hit the accounts endpoint repeatedly for every location to see what accounts the user has available and then ask them to choose the appropriate account.

It would be nice if there was an API endpoint that would just list all of the users accounts in a single shot.
