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

New arbiter that further improves performance by removing latency for instruction memory access. Created instability again, which I found to be caused by bad interrupt timings. Fixed by changing the interruptValid wire to use branch_MEM for alignment. I do not know why this fixed all problems as it is very hard to simulate this issue. L1 cache should be possible again!

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.
