Update to bsnes v033r07? release.

And another one.

I've re-written the DMA state machine. I decided to keep it in one FSM
instead of two separate ones, because they honestly share so much. But
I rewrote it to be a lot cleaner, and to handle some really
exceptional edge cases. Due to the design, I was even able to make the
HDMA during DMA edge case "transparent", eg the same codepath is used
for normal HDMA and for HDMA during DMA :D

New WIP passes the last four tests in test_hdmatiming.smc. The ROM
posted doesn't validate the last four yet, so you have to compare the
SRAM file to the source logged values if you care to.

That should be everything with DMA and HDMA timing now, thankfully.
Really happy with that codepath for the very first time. Such an
improvement from the "don't even worry about HDMA syncing" code I had
a few versions ago.

I also reduced the DRAM refresh rotation from 7-lines of code testing
against the NTSC color burst case to 1-line, using the DMA counter
(dram_refresh_pos = 530 + 8 - dma_counter())

Lastly, I added a flush command to the status bar. Any important
messages will now flush all buffered ones to display the new one. Eg
load 10 games back-to-back and it'll say the name of the new game
immediately, instead of scrolling through the other 9. It will still
buffer lesser important ones, like unsupported chip and UPS patch
applied messages. I also removed config / locale path display, because
it annoyed me.

Nearing a release. I want to state machine neviksti's SPC7110
decompression code, and I should be ready on my end.

FitzRoy, I'll give you the final word. If you want controller port
selection moved to "System", I'll do so.

Any show stoppers should be mentioned now. I can't fix the "crash with
Unicode characters in the executable path" issue just yet, so that'll
have to wait.
