started 07.02.2006

Changelog:
v1      Entire game written and compiled, works like a charm
v1.1    Added the Build Village function. Fixed a few typos and one bug.
v1.2    Added magic attacks (more will come) and the shop to buy items (only health refills for now)
v1.3    Bug fixes and mana potions available at shop
v1.4    Monsters drop money (1-20), magic books in shop, bugfix (magicLevel added up after every fight)
v1.4.1  Shop Code rewritten to use switch instead of an if statement. Therefore it can be located in its own function (doesn't need to call on main() anymore)
