1cc7e32e2d Fix handling of tokens consisting of separator characters 
The parser is no longer hard-coded to skip whitespace. Tokens
such as newlines, whose characters overlap with the separator
characters, can now be correctly recognized.

2a222adb7e Represent character sets with unsigned chars 
This is better for comparing character ranges, since
there is a definite maximum character value.

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

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).
