Move control unit to its folder
First try of forwarding unit
Even simpler test
Personal wave.do file added to gitignore
Add forwarding unit to DLX
It seemed to me that the register file was not working properly.
This could be caused by incorrect timing of the signals, as the RF stage is self-clocked (and so control signals cannot arrive at the same time as the clock
edge).

So, I started changing the signals arriving at the RF stage to be latched and not clocked by means of a flip-flop (as Matteo suggested in the last meeting).
It turned out that this was not the cause of the problem (see next commit), but this job should have been done now or whenever, so that's it :)
RF incorrect behaviour was caused by wrong reset polarity (ehm..)
