http extension - various improvements
http extension - various improvements

- introduce more "static" methods where possible to improve performance
- remove "charset" parameters where unappropriate, this means everything which is URI/URL-related is always UTF-8
- introduce JSON-based GET requests

I have done extensive testing with various types of requests (GET/POST) with different formats (JSON/XML/urlencoded) and everything worked fine.
I used Jolie http clients, curl and different webbrowsers.
