Adding vga_graphics that implements double buffer

How to use:
1) File contains a draw-bomb function, which can serve as blue print for
functions for drawing animated shit on the screen. Rejoice!

2) Best used in conjunction with seperate functions (i.e. do not change
the function order in the main() or I will personally give you a death
stare.

3) But seriously, create drawing function from blueprint (look line
119,120 and 121). Put this shit like its a pricetag for everything you
draw that is supposed to move (it just flips the buffers for the
smoooothieness)

4) Such Questions. Much Kris. so ask.
