v2 testing release

This basically just fixes the desktop file

IF YOU GET A WHITE SCREEN, you forgot to perform the manual file copying workaround. See the README or issues for more info

testing version 1

Note for anyone recreating this: you need to copy wwwroot and grayjay.png from the extracted zip file into the user data location (ptobably .var/app/app.grayjay.Desktop/data/Grayjay) in order for it to work. This is an ugly hack that is so ugly i didn't want to automate it becuase i dont want to automatically pollute peoples data directories with stuff that shouldnt be there
