Also includes following changes:
- Fix for rocketcgi library to accept POST data content-types, which contain additional charset information.
- Support arrays passed as params to encode.url (only for keys ending with "[]")
- Version information changed to "1.0.7"
Documentation for added functions is not yet complete.
