0.3

Here is version 0.3. I was intending for this update to include many new features, including a magic system. However, to get bugfixes and performance improvements out as quickly as possible I have brought this release forward. 0.4 will be a much more significant update. 

• Many bugs killed. Performance improved.
• The Village. You now start in a village with NPCs and can return here.
• NPCs. Currently all you can do with NPCs is trade. More to come in 0.4.
• Balancing.
