Basic CPU design now done with afaik working hazard detection, forwarding and stalls. Tested in hardware on a EP4CE6 using two SSDisplays and dip switches to view the register content (and see if it matches the simulation). No interrupts yet as this can probably be done at a later stage.

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

Register forwarding now works for ALU operations, (memread getintid and savpc still needs forwarding). Regbank is simplified because no need for we_high anymore, load and loadhi are now done using an ALU operation.
