v2.3

So much good stuff, thank you Raja!

• You can now use thread_per_connection
• SSL, wat? This is still highly experimental, BTW. It crashes mysteriously some times.
• Apparently some people—Raja—want to return headers in a response. Done!
• And the methods for adding and removing handlers wasn't thread safe. Now it is!
• Finally, when things hit the fan, you can enable_debugging to get MHD errors dumped to std_err. Which is pretty crappy, but you just wait until we figure out a cool way to make that better

2.0

• Changed parameters to request handlers to accept a single request object that contains the regex matches, parameters, request headers, and request body

v1.1.0

Added support for receiving JSON data in the request body for POST requests. It can be accessed, if available, through params['json_data'] in your request handlers.
