Fixed bug that caused the add/edit screen of homework to not work on non-debug builds.

Added predictive back gestures (show what a back action does).
Enable minify.
You can now rename channel links (discord relations).
Discord relations are now called "channel links".
Added warning for mitm attack when using app in the web (or as webapp), whilst beautifying README

 **If you are on android** and do not mind the debug certificate go ahead to releases and download your arch.
 
 **If you are on ios**, download the ipa (native app) in the releases, if you know how to install it. This is again not really signed. I would recommend Alt-/Troll-/Sidestore. When Apple allows apps to finally be installed like on android, then do it that way.
