why wasn't saving there from the start?

The game jam version didn't have saving. That kinda sucked. Especially since adding it was easy.

Changes:

• Set limits on item price changes (no more ¤0 items)
• Documented that pressing "End" in the root menu jumps to "Advance Day"
• Added saving. Save file is stored in %appdata% or ~/.local/share
• Removed traces of scrapped MP stat
• Slight rebalancing of low-level dungeons

More later, maybe.
