v0.1.0a - A new weapon and lots of fixes!

I've added a new Weapon:
The Spear!

Poke the monster for fast and light damage, throw it for heavier damage, but be careful - what's thrown has to be retreived!
The spear can get stuck in a monster, and it might just run off with it, leaving you without your weapon.

I still need to tweak the sound (picosystem only so far, sorry), and damage and cooldowns - right now it's a little overpowered.

The sword also got a bit of an overhaul:
You can now charge your attack by pressing A, and do a stab attack with X.
