WON viewroll (bxt_viewroll?)

The only important thing I would like for that is to make it not override viewangles for the demo file, otherwise I disagree to accepting that changes. (because that can cause a lot of issues, for example, moderators who verify the run, or if I want to render demo with a normal settings of someone who played with the viewroll)
