- splitted 'cashonly' into two separate apps named 'cashonly.web' and
'cashonly.core'
- added a service layer as a place for business logic related to the Account
model
- adapted admin and web functionality to use the new AccountManager from the
service layer
- added a debit_limit field to the Account model in order to get rid of the
formerly hard-coded default
- probably other changes that I've forgotten to mention
Ther are likely some bugs and TODOs still left behind
