This fixes an issue where certain configuration options were ignored if their internal name started with "group_". As a result, affected settings in areas such as CRM and general system configuration are now properly recognized and applied.

ISSUE : https://www.odoo.com/web#id=647027&view_type=form&model=project.issue&action=963&active_id=681

Check printing is reorganized so shared functions are available behind the scenes while user-facing print options appear only when a specific check printing module is installed. Users also gain an easier way to return check payments from sent to posted, and amount-in-words is no longer shown where it should be hidden.

- Module account_check_writing becomes account_check_printing, a hidden dependency for modules which provide check templates
- Payments by check have a button to go back from state 'sent' to 'posted'
- Amount in words is hidden
