json requests and web requests timeout

[foretagsplatsen]

I have done some modifications for the following issues:

• The ability to send JSON data, i.e. Content-type = "application/json" without form encoded body
• Huge requests, i.e. a big request body and long timeouts on the webrequests.

So what do you say about the changes? What needs to be done to get it pulled into the master? I tried to follow the design but I guess there is a lot of improvements that can be done.

Oh, by the way! Hi and thanks for the great work you have done! :-)

Best regards Mikael

I got a bunch of conflicts trying to merge this with master, are you able to take a look.. I believe master has changed a bit since you submitted this pull request.
