Awesome animation!

Weird issue going left and up but looks pretty good at 100ms movement. 1
step closer to victory!

CHANGES:
Character.java:
*Added moveTimer and currentMoveTimer that keep track of its position in
the movement.

*Sloppily added prevTile to be stored to keep track the previous tile
this character visited for animations.

*Modified charMove() to work with these new variables.

DungeonMain.java:
*Fixed xPos and yPos int animateMovement by casting to double.

*Using xPos and yPos and the centerTile, get the x and y coordinates for
each character.

*Sloppily copy pasted drawing code for animation. I really should modify
the source images.

*In run(), I added the moveTimer variable for moving characters. Note
that it counts up unlike hitTimer which counts down.
