Deck editor improvement, fix for missing cards and relics

File->Exit works now

Some regex corrections from @laxdog (thank you!) for some missing cards and relics.

Adding/Removing Cards is much less horrible, it is still not good but it's not ridiculously broken.

Works better in Linux; as-in it doesn't crash. Install is pretty nasty, I'll fix that at some point.

Potions

Adds Potions Add/Remove, it also makes some effort to also obey the number of potion_slots available

Getting started

Settings, Cards, Relics.. all good-ish. Potions, not so much. Windows installer... maybe it works?
