Added abort download
Added Update shortcut (F5) with 24h limitation/type (should probably fix this to save the DateTime somewhere instead of initializing it directly as "now" everytime... (you need to have it open for 24h before you can update right now!)
Did a few cleanups here and there...
Removed device prep stuff, will add this as a plugin later instead...
Added Plugin design work...
