[mythtvnz] SkyStar card & MythTV setup documentation

[Craig Box]

I bought a SkyStar 2 card today.  Didn't take long to set it up with
Freeview, mostly thanks to the docs at pvr.geek.nz.  As they were almost
over my head, they'll undoubtedly be over the heads of many others, so
I've simplified them, and rolled in some required changes.  It's all
written up:
