Work in progress for release v1.7/1.8

This is a refactoring of the entire Inky-Calendar software and is work in progress. The reason for uploading is to test if everything works fine. Please do not attempt to use/install this software as it can potentially break your system. If you have any improvement ideas, you're most welcome to mention them in the Issues section. Thanks!
