Window positioning blocks

[gomigg07]

Blocks that can change the position of the game window if run on desktop (think like Rhythm Doctor)

center window to desktop

set window x/y to ( )

change window x/y to ( )

set window width/height to ( )

set window align center/left/right

this can be used with runtime options "stage size" functions in order to make some cool effects
