Add Separate View Bob Sliders for Plaza/Condo, Virus, & SDNL

If/when view bob support is added for the Plaza/Condos, it would be nice to have several different sliders for the Plaza, Virus, and SDNL, since I would want to have it lower in the Plaza and higher in Virus and SDNL and it would be a bit lame to have to keep switching my view bob intensity depending on what I want to play
