Minor Hotfixes 0.2.0.13

Should hopefully be the last batch of quick updates before I can take a break. [list] [*] Updated the Fluffy Nut icon so it doesn't look so much like Copper Ore. [*] Added a new drink to Ryan's Monster Foods. [*] Added a confirmation dialog when ending a dungeon early. [*] Added a cancel button to Contracts in the Notes panel (although the person who put the contract up won't like it) [*] Rebalanced Transporters and some other machines to make them more useful. [*] Rebalanced the reputation gained from contracts to make Ranks 3-7 less of a brick wall. [/list]
