TODO: r4300i/core

• clean up Win32 filth from core. This means clear abstraction. vital for bizhawk/rerecording.
• change all types to sane types from main.h
• change as much as possible to portable equivalents
• work on timing (remove counter factor?)
• try make things more bulletproof for rerecording/bizhawk.
• remove RSP/audio interface
• fix broken opcodes/timing/etc/overall accuracy gui:
• add 7zip support (possibly via File_Extractor) RSP:
• integrate into main executable (remove selectable RSPs)
• fix broken opcodes/add missing audio:
• add audio output method to replace plugins rdp:
• way too much to do.
