byuu a8263afc24 Update to bsnes v060 release.
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]
    - fixed a signal issue that caused loading games to take 1-2 seconds longer in v059
    - 21fx API revised to its final form, S-MSU (public documentation pending)
    - worked around QTBUG-7188 to fix multi-file 7-zip file listbox to update when scrolling
    - added scale max - normal, wide, and wide zoom modes to fullscreen mode
    - added overscan cropping tool (needed for wide zoom mode; useful for developers simulating games on a real TV)
    - added "go up one folder" button to file load dialog
    - added group (un)assignment to the input settings window
    - now honors input.allowInvalidInput setting; defaults to false [Jonas Quinn]
    - cheat code editor grays out empty slots
    - cheat code editor adds "clear selected" button to quickly erase multiple cheat codes
    - to load folders as game images, folders must end in .sfc, .bs, .st, .gb now
    - debugger: added S-CPU (H)DMA registers; S-SMP registers; S-DSP registers to properties list
    - snesfilter: HQ2x filter is now multi-threaded (scales infinitely: the more cores you have, the less overhead required)
    - pixelshaders: added screen curvature shader to simulate curved CRT tubes
    - source: lots of code cleanup, as always
