Beta Branch - Bug fixes and balancing

This is a teensy tiny little beta update to balance a few headaches at the start of the game and fix some bugs. [list] [*] Purchasing items is about 25% cheaper [*] The price of food and drink items have been reduced even further [*] The duration of a day has been increased to around 20 minutes [*] Players can now choose between 3 different day durations when creating a character (20, 25, 30 min) [*] Reduced the Fuel cost to produce Coke, so it will always yield more Fuel than you put in [*] A new Paper item can be found in the first level of the Ruins [*] A new fish can be caught in the pond on your property, it can also be caught by using one of Pete's Basic Lures [*] Optimized the way items are added to the Researchler, which can prevent lock ups when adding lots of items [*] Fixed a bug that caused Theseus to get stuck in a wall when loading a saved game [/list] Special thanks to everyone on the discussion board for these bug reports and suggestions! This update will sit on the beta branch for a few days for additional testing and then will be merged into the main game.
