Evented Fiber-aware Ruby webserver

Rity is a lightweight Ruby webserver that runs inside an EventMachine loop and puts each request into a fiber.

TODO

• Command Line Interface
• Let Request handle parsing and building errors
• More robust error handling in general
• Proxying via EM.enable_proxy
• Rack Handler
• Support for keep-alive connections
• Investigate MVM support in JRuby/Rubinius/MRI
• Support for SPDY
