allscreens extension

[Nikos Vassiliadis]

Hi,

I am using this small addition to etc/rc.d/syscons.
It extends the allscreens functionality with an
allscreens_exclude variable which controls the virtual
terminals that are excluded from running the allscreens
command. I use it mainly to exclude ttyv0 from switching
to raster mode while allscreens are set to raster mode.

I can file a proper PR if that sounds interesting to the project?
