Alpha v5.0 in progress

With any luck, Alpha v5.0 should be out in the next few days.
What I'm working on:
- New items (fish, floor loot, mob drops)
- 5 new stats
- 2 new unlockable characters (you can already see their achievements on Steam... also has hints at two of the new stats)
- Quality of life changes (biggest one is pressing f to use any item, including those on the floor)
