Move tweens now just use quadout instead of inout.

Made shaders a class to make it easier to add more in future.
Added shaders for updown and downup fades.
Fix loading characters with no pattern (e.g. black_mask) not working.
Gave ability to cancel lerps in case a character gets put on then immediately faded to another alpha.
