05e16a8c46 Remove ordering of parse and lex items
Using an unordered_map and unordered_set to store these
speeds up grammar compilation significantly. The ordering
method on items was using the rules' .to_string method to
compute the order, which was not a meaningful comparison,
and was probably slow.

80b19cbb83 Construct entire parse table statically
This removes the need for the 'init_parse_table' function,
which was not really thread safe

2df56f01c8 Remove public hidden symbol function
Now, you can't a particular occurrence of a symbol
in a grammar. You can only hide a symbol globally
(right now, by beginning its name with an underscore).

48baf056b4 Store grammars' rules in vectors, not maps
This way, we can keep of the order in which the rules
were given, for resolving reduce/reduce conflicts.

67b33a615b Refactor generated parsers to used explicit table
This is slightly slower than encoding the parse table in
flow control, but allows the parser to inspect the parse
table more flexibly. This is needed for incremental parsing.
