Long overdue maintenance

Due to some great contributions I'm happy to announce a new release of http-proxy containing numerous bug fixes, feature additions and documentation improvements. Thanks to all who contributed for their patience and willingness to contribute despite perceived stagnation in activity in the project. I welcome all contributions and those who are interested in getting more involved with the project. Below I will highlight the changes that landed in the latest version but you can find the full diff of the changes in nodejitsu/node-http-proxy#1251

• Add option to rewrite path of set-cookie headers. @​swillis12
• Add option for overriding http METHOD when proxying request @​AydinChavez
• Feature: selfHandleResponse for taking responsibility in returning your own response when listening on the proxyRes event. @​cpd0101 @​guoxiangyang
• Add followRedirects option @​n30n0v
• Document timeout option @​jlaamanen
• Fix documentation typos @​carpsareokiguess
• Document buffer option @​jonhunter1977
• Include websocket non-upgrade response instead of just closing the socket. Allows auth schemes to be possible with websocket proxying. @​Tigge

• Be more defensive in handling of detecting response state when proxying @​thiagobustamante
