giles 4c84decc01 search: Phase 2 query parser + 32 tests ...

Query tokenizer + recursive-descent parser: OR<AND<NOT precedence, implicit AND
on adjacency, quoted phrases, parens, case-insensitive keywords. parseQuery,
searchQuery, showQ. Worked around haskell-on-sx parser limits (ord-based
delimiters; multi-clause fns instead of []-pattern case alts). 78/78.
