ROL support for 64bit VPinMAME

[toxieainc]

From https://github.com/vpinball/vpinball/issues/81 :

"I use single screen in portait, so I need to rotate DMD to get it right. When I set ROL=1, DMD is just black. with ROL=0 it works normally. Same settings with 10.6 DMD works with no problems while rotated.

UPDATE: found out the 64bit Vpinmame is bugged and doesn't support ROL. (black screen) chaning VPX 10.7 to 32bit solved the issue."

still valid for 10.8rc1 x64. rotated internal dmds are black.
