Shortened the ColorSwap method
Added score counter to Tetris.ahk
Fixed small score display bug by right-alignment

Before, if you somehow lost points from 145 to 0, it'd show up as 045.
By doing what I've done, it'll replace "145" with "  0", which will
reset the extra numbers, too.
Fixed console buffers to work with ANSI AHK
Fixed Tetris.ahk to work with ANSI AHK
Added SetColor in Tetris for consistent score color
