Update to bsnes v021 release.

This is a maintainence release. I am mostly releasing this for the sake of the recently released Der Langrisser translation. Changelog: Windows port can once again map joypads through the Input Configuration panel Using enter or spacebar to assign a key should no longer instantly map those keys F11 now toggles fullscreen mode Esc now toggles menu on and off (use F11+Esc combined to hide UI completely) Fixed a bug in King of Dragons (J, U, E), KOFF was not cleared during S-DSP power(), thanks to FitzRoy for the report, and blargg for assistance fixing the bug Fixed serious crashing error with File->Load on Linux/amd64 port Hopefully fixed min/max undefined error on GCC 4.2.0, but I am unable to test to verify Fixed many cast const char* to char* warnings for GCC 4.2.0, but some probably remain, as again, I am unable to test as I lack GCC 4.2.0 Set XV_AUTO_COLORKEY to 1 for Video/Xv renderer. Should fix some video drivers where there was no output, especially after running mplayer, etc. Thanks to sinimas for the fix Added clear_video() to Video/Xv renderer. Green edges at the bottom and right sides of the video output are now gone, and unloading a ROM will clear video I have finally figured out how to poll the keyboard status in real-time through Xorg: the XQueryKeymap function. I will be rewriting the Linux key capture system to use this, instead of capturing window key up / down messages through GTK+. This will finally allow me to completely abstract the UI from the hardware video, audio and input interfaces: a necessary step toward Linux joypad support.
Update to bsnes v020 01 release.

-/* Notes about PAL timing:
- * As I do not have PAL hardware to run timing tests on, I've
- * had to guess on a lot of things. Below is how I've arrived
- * at various calculations:
- *
- * NTSC timing crystal: ~21477272hz
- * PAL  timing crystal: ~21281370hz
- * NTSC ~60fps, PAL ~50fps
- * NTSC ~262 lines/frame, PAL ~312 lines/frame
- * NTSC 21477272 / (262 * 60) = ~1366 cycles/line
- * PAL  21281370 / (312 * 50) = ~1364 cycles/line
- *
- * As the cycles/line are very close between the two systems,
- * I have left the known NTSC anomalies intact for PAL timing.
- * In reality, some of these may not exist, and some may be
- * slightly different.
- *
- * [known]
- * - DRAM refresh occurs at about the same time every
- * scanline on PAL units (per Overload).
- * [unknown]
- * - Are dots 323/327 still 2 cycles longer than the
- * other dots?
- * - Is scanline 240 on non-interlace odd frames still
- * 4 cycles short?
