Removed a lot of in my opinion redundant information and cropped pictures to make the docs a lot less overwhelming. For example information on version 0.7.1 and the long list of individual features.

Reorganized, moved and split information, so the topics are more "contained"

The best way to check these changes would probably be to browse the repo here https://github.com/Riksu9000/InfiniTime/tree/update-docs
