Fix a few formatting issues

Fixed a few files that went over 80 columns, mostly just a nitpack on my
part.

libobs/obs-nix.c had a rather bad case of leading whitespace.

Also, fixed the x86 obs-studio project files so that it would properly
output to the right directory.  It couldn't find libobs.lib because
obs-studio's project settings had it outputting to a different place
than the rest of the projects.
