moved a lot of stuff and changed the scripts

Changed the structure of the directory from

nysa/cbuilder/rtl to nysa/cbuilder/verilog

it makes more sense because rtl is only synthesizable, which is what the
previous version had but in order to implement simulation I had to use
simlinks to connect the two unfortunately simlinks don't work across all
platforms. So this new directory structure handles this better by localizing
the simulation directory right next to the rtl.

the build structure primarily uses scons now instead of make. It is a lot easier
to use compared to Makefile... well there is a little growing pains with it
but it looks very promising
added the first part of ibuilder

As I added it I found there were way too many dependencies on the ibuilder
script folder to just work in the GUI so I've switched my focus for a bit
cause I need to get the ibuilder scripts implemented on Nysa
Migrating from olympus ibuilder to nysa ibuilder

The migration is not straight forward because the ibuilder scripts
were not initially done well because I was very new to Python

The unit tests are not all passing and I need to work through all of them
before I can start with the ibuilder ninja plugin
added ignore for simulation and vcd files
