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.

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.

were given, for resolving reduce/reduce conflicts.
