Update to bsnes v021r01? release.

Alright, I've posted the new WIP.

             This one's really important, so please test it
thoroughly! :D
 I've ran it through my usual list of troublesome games, and
everything looks good, but it's possible I've overlooked something.

             The new config file settings are:
             ppu.hack.oam_address_invalidation
             ppu.hack.cgram_address_invalidation

 Set to true, OAM goes to 0x0218 (for Uniracers), CGRAM to 0x0000
(address is insignificant, we know of zero examples of this behavior,
so the address chosen does not matter for now). Set to false, the
writes are allowed and go where 'expected' (by programmers, not by
hardware).

 There's a slight difference in that OAM access is invalid even during
hblank, whereas CGRAM is obviously not (that's how games draw those
gradient fades and such).

             This WIP also has the Lemmings II fix.

             ---

 Now, I know I said I wouldn't bring this up again, but meh. So,
assuming I decide to go full force at this PPU renderer ... I still
want to let bsnes live on in its' current form, even if that means
losing my userbase to a competitor :(
 I'm planning for the next release to allow derivative works, in hopes
that someone will continue it. Does anyone have any objections to
that? Would it be better to use GPLv2/3 to ensure source availability
(even though I disagree with the notion of 'freedom through
restrictions' -- I liken it to becoming your enemies to defeat them),
or better to use PD to ensure the widest possible use of the code
(even if that means the source can be closed off to the public, and
the binary sold for profit -- which I also detest as immoral)? I
realize the latter means the value of all of my work will be lost, but
I never intended to profit from any of this anyway, so ...

 If you prefer GPL, please specify either v2 only, v2+ or v3. I can
use v3 and grant ZSNES an exception to use it under v2, so their v2
only license won't be a problem.

             Some examples:
             ZSNES is GPLv2, which got them the source to Zsnexbox.
 PocketNES is PD, which got the emulator used in commercial software
by Atlus, Hudson and Jaleco (though the assholes couldn't even be
bothered to send a thank you letter to the PocketNES devs).

 EDIT: I can also stick with the current license, a no-derivative one,
and do my best to maintain bsnes' old PPU renderer, if you like. But I
won't lie ... the pace of development _will_ slow down a lot on the
older version (it shouldn't affect my new PPU development speed much)
if we go with this option.

             Once again, I'll go with community opinion this time. I'm
personally not casting a vote for either.
