Proto live mode

[aeaster667]

Live mode allows any character in the loaded household (1-8 ponies allowed) to be playable. The game should recognize the active character and other playable characters as the only ones living in that lot, and to allow the active character status to be switched from one to another. A basic motives system should be in place, controlling every character's moods, which certain interact-able objects will affect the status of. Also a very simple version of a relationships system should be created, so when characters interact with each other, it modifies the relationship value with each other (0 being the centerpoint, -100 being the lowest and 100 being the highest).
