SF2000 Multicore Alpha 0.10

changes in 0.10:

There are now several choices of cores for some systems. It's up to you to pick the ones you want to use!

Recommended choices:

• Amstrad: amstradb (Caprice32)
• C64: c64 (Vice c64)
• GB/SGB: gbgb (Gearboy)
• GBC: gb (TGB Dual)
• GBA: gba (gpSP)
• Lynx: lnx (Handy)
• NES: nesq (QuickNES) for most games; nes (FCEUmm) for FDS games and the rest
• SNES: snes (Snes9x 2005) for most games; snes9x02 (Snes9x 2002) for certain slow games
  Note: the only stock emulator without a better multicore option is the Arcade section

We're considering these changes for a future release:

• remove amstrad (CrocoDS), built-in menu hangs when used for most things, Caprice32 seems fully functional alternative
• rename amstradb (Caprice32) to amstrad; if there's reason to keep CrocoDS, rename it to amstradb
• rename gbgb (Gearboy) to gb; make it main GB emulator; keep TGB Dual as gbc for Game Boy Color only
• remove gbav (VBA Next), it is slower than stock GBA emulator and gpSP core
• remove mgba (mGBA), it is slower than stock GBA emulator and gpSP core
• remove c64f and c64fc (Frodo and FrodoSC), they are slower than Vice x64 and Vice x64sc
• remove lnxb (Beetle Lynx), it is slower than Handy
• rename nesq (QuickNES) to nes; make it main NES emulator; keep FCEUmm as fds only for Nintendo FDS emulation
• remove nest (Nestopia), it is slower than stock NES emulator and the other NES cores

• fixed Caprice32; increased brightness (opt file setting)

Internals (affecting all cores)

• kobil: new opt behavior: multicore.opt is global settings file that applies to all cores
• kobil: new logging behavior: only log when a log file already exists (so delete the file to disable logging)
