Implement form-urlencoded support

Browse source 
Query and form return a Hash, folding duplicates with last-key-wins
strategy. *_array methods provide the seldom-used duplicate-preserving
counterparts.

Keep query and form separate, but provide params, which handles
both, with form having precedence over query.
