trillium-http-v0.3.9

Bugfixes:

• 3396bc2 case insensitive header equality was wrong

😞 This mistake performed exact string comparison instead of doing what the method name claimed — case-insensitive comparison

Features:

• 8a1ce38 adds Headers::remove_all
• b855039 treat Connect as an Upgrade so it can be proxied
• 1d4a6d8 adds Conn::path_and_query
