First alpha release of Bookable Resources.
Book rooms, instruments or any shared resource on a timeline calendar, with optional approvals, recurring bookings, opening hours and holidays, equipment, maintenance blocks, email notifications and reminders, CSV import/export, skins and in-site help.
This is an alpha: the module is complete and covered by an extensive automated test suite, but the data model and APIs may still change before the beta. Please try it and report anything you find in the issue queue.
