Fully implemented interrupts in verilog. Return address appears to work fine, but might need some further testing for different delays in the pipeline.

Added back scripts for converting to spi.txt. Tested code to run from SPI flash, fixed cycle delay for SPI flash in output latch in MU which caused the bus_q to arrive a cycle later than bus_done.

Added MU from FPGC5, created arbiter to regulate access to the CPU memory bus from both Instruction and Data memory, created fast testbench for arbiter, can now start adding arbiter and MU to CPU design

Forwarding now also works for data memory and also probably branches and other MEM operations. Fixed a bug in forwarding where EX was used instead of WB

Jump flush now seems to work. Made simple Quartus project to test in hardware and it seems to work fine there as well

Started working on the CPU pipeline. Basic load, arith and jumps seem to work now. No hazard handling yet.
