[NTG-context] MikTeX and XeTeX now available

Dear all MikTeX fans, Just to let you know: MikTeX 2.7 beta 3 should work OK with ConTeXt & XeTeX (with yesterday's ConTeXt update). I have experienced some problems with fontconfig & admin rights, but in general it could or should be OK (I didn't try the very latest version). If you experience any problems, they should be reported. Mojca PS for Hans: the -tcx flag removal has been implemented at exactly the right moment, since it doesn't work on MikTeX under windows.
