Add grammar.py for generating compiler-compilers
...
grammar.py is meant as a compiler compiler compiler, taking in a grammar
structure and returning flex and bison files. It can also parse EBNF.
Currently there are still remnants of VHDL-specific stuff in the code,
because parsing VHDL was what it was initially about.

ShuntingYard.py: Improve tokenize() quote handling
...
Quoted arguments were not grouped into one token, firstly, because the
parser didn't pay any attention to them, and secondly, because the data
structure carrying the postfixed string converted it back to being a
string, not a list, in column 2 of the result table.

This was a namedtuple before, but I couldn't figure out how to ex-/import it
over module boundaries, so I've made it a class.
