New SDRAM controller that uses both SDRAM chips. Now separate bus from MU for better performance, as controller runs at 100MHz. Also updated some debug code as debugging was needed. Tested working in hardware. 2x performance boost in some cases.

Fixed more MU I/O bugs. Updated everything from BCC except the ASM to work on new CPU. Added back flasher programs. Fixed LOAD/HI bug by using unsigned const16 instead. Updated assembler including hotfix for FPGC jumping to addr3 after UART bootloader is done. FPGC6 now basically fully works again!

Assembler only needs Int: function, fixed position of program lenght. Ported ROM and UART bootloader over from FPGC5. Updated documentation on interrupts. Added resets. Fixed bug in MU. Increased stack size. Tested everything in hardware. Probably some other fixes and things I forgot.

Created full FPGC6 verilog simulation, added Quartus code from FPGC5 with CPU from FPGC6. Works in hardware, but has combination loop somewhere at the arbiter and the registerbank and stack are not using block ram
