V 0.2.2 optimizations

Took care of some minor draw backs to performance, by: allotting hunger and thirst to squirrels. They now exhibit targeting behaviors to say, get food and water, and attack.

I've added in voles, static still, as they are not programed to do much but spawn at the creek areas.

Moving into 0.2.3 I will be adding more creek areas to the game's map.

I am contemplating adding in a bird of some kind, to give the aesthetics a bit of a lift.

The character reference sheet is slimmed up and i've correctly added 'D' to the damage and defense roll print out.

The damage delivered and recieved are now a print out on the hud.

Accorns can be collected for a tad of hp and hunger.

I will be adding a hunger and thirst meter going into 0.2.3.

Hoping by maybe today to have 0.2.3 live, before the midnight build.
