Rewrite entirety of code - methodise everything

[jpwilliams]

Code needs to be properly structured and regimented with a selection of classes managing the different areas (Projects, Towns etc). Each class should contain an array of methods that'll be used in event handlers and the like.

Towns, for example, will have methods such as:

createTown
removeTown
listTowns
getPrice
playerBuying
playerSelling
increaseStock
decreaseStock
getItemInfo

This will be a lengthy process, but should improve the code readability ten-fold. More, in fact.
