0.21.0

Behaviour change: when a URL already has a query string, params (client-level, then per-request) are now appended after it, matching requests. A key present in both is sent twice rather than replaced: ?a=1&b=1 with params={"b": "2"} now sends a=1&b=1&b=2 (previously a=1&b=2). The URL's own query is also sent byte for byte instead of re-encoded (?q=a%20b no longer becomes q=a+b). See #156.
