Title: add limited sprite duplication functionality

Instead of providing colors & sprite matrix, you can instead copy/rotate/flip previous sprites, like so:

GunUSingle U
Black Grey Yellow
..0..
12021
11011
11111
.111.

GunRSingle R
rotate GunUSingle right

GunDSingle D
rotate GunUSingle half

GunLSingle L
rotate GunUSingle left

This eliminates tedious copying when there are multiple orientations of an object.

(Also fix a minor case sensitivity issue)
