Second alpha of casmeleon v2.0.0

Multiple bugs fixed, added verilog compatible export (flag -export=bin)

Casmeleon v2

Initial alpha for casmeleon version 2, mostly works, a few bug may happen, debug support is quite limited, do not run this in production.
I am joking of course, no one ever ran this in production to begin with.
