bsnes v060 released 2010-02-08

This is a long-term stable release. A full changelog will be available at the forum link below later in the day. Also, please note that I have merged all of the various distributions into two packages. The Windows binary package now contains both the profile-optimized (fast) build, and the debugger build. The source code package now contains sources for bsnes, snesreader, snesfilter and supergameboy.

Changelog:
* added Direct3D HLSL pixel shader support [mudlord]

* worked around QTBUG-7188 to fix multi-file 7-zip file listbox to update when scrolling
