theme: force Fusion style on platforms other than Win32 or OS X I was reluctant to do this, but most of the other styles just look like pure shite regardless of whether I force a stylesheet on them or not. KDE's style is actually hilariously bad paired with my stylesheet, so I've decided to also make the stylesheet Windows-specific as well, because that's really the only platform where it makes sense in the first place.
