NES - mapper 231 - optimize the ReadPRG() method

-Fixed the memory mapping. I don't know why I thought I'd be able to just mask addresses to the length of the segment and think it'd work...
...
-Tried two methods of parsing the ROM file. Neither of them worked.

-Made Intellicart its own class.
...
-Separated cartridge logic into a separate ICart named Cartridge.cs.
-Made WriteMemory return a bool to match ICart.Write. It currently returns true if either the cart or the core responded.
TODO: Parse the vanilla Intellivision ROM, which will hopefully include the read / writability of the data segments. adelikat seems to think that I just need to send the bytes to $5000, but I'm not convinced.

NES - fix mapper 96 prg mapping. These games are working as well as can be tested without better peripheral support, so I'm considering this mapper complete.

NES - progress on mapper 96, Oeka Kids - Anpanman no Hiragana Daisuki seems to play (but I can't get passed the title screen without Oeka Kids tablet emulation). Oeka Kids - Anpanman to Oekaki Shiyou!! fails to load (suggesting a PRG mapping problem?)

Started filling the gaps in the Memory Map, getting up to 0x7FFF. Once complete, a lot of TODOs remain, the most important being the actual mapping of the cartridge.

-Logging now uses a static StreamWriter instead of building the string and writing on destruction.
...
-Applied to the old Gameboy core. Why not? It at least fixes that annoying bug from before if we ever care to use it again.
-Both logs are now written to different files.

-Fixed logging.
...
--It now just builds a strings and writes on finalization.
-Fixed up format strings.
-As RegisterPC already increments upon reading the third decle, I now just store PC as the return address for jumping instead of PC + 1.

-Refactored of the executor / disassembler / Intellicart to use more descriptive variable names and types to clear up a lot of confusion.
...
-Added implementation for NOP (6 cycles of nothing).
-Made SWAP actually store the result (Still disabled).
-Added breaks to the swap / shift / rotate cases (Yikes).
Instruction disassembly:

-Made MVI@ and ADD@ follow the stack and immediate mode rules for incrementing / decrementing the SP / PC.
...
-Disabled Intellicart hook for ReadMemory, which seemed to be interfering.
-Implemented MVO@.
-Several instructions are now executed in succession until it hits the unimplemented "XORR R5, R5".
I should probably refactor Disassemble and Execute to label registers as source / destination to avoid further confusion at some point. My disassembly might have the source / destination registers flipped as well.
