v2.0.1 available

Small bug fix and added favicon!

The latest minor release includes a bugfix for issues that some people may have when upgrading from version 1, in that the days that periods are configued on are shifted by one day.

This update should address this problem on existing installations, and should also work for new upgrades from v1. After updating to this version, please check your period configuration have the correct days assigned.

It also adds a 'favicon' of the new branding, to help distinguish classroombookings in browser tabs and windows.
