VM xorg.conf template: properly set H/Vsync and Modeline

[marmarek]

On high definition displays (e.g. 1600x900) the dummy driver we use in AppVMs refuses to accept the high resolutions, because hsync param being out of range.

We should figure out a correct way how to set hsync/vsync and modeline params for the vm dummy xorg driver, so that it always happily accept the resolution that the use has in Dom0.

But, there still might be a problem with display having more than 2048 pixels width (e.g. large 30" ones), as apparently the dummy drv has a hardcoded check. Seems like we will need to import dummy_drv into our gui.git and patch it there, and use this driver (qubes_dummy) instead of the original one.
