Added partial request printing functions

[foxfriends]

Was having trouble sending GET requests with this properly as the only "query only" string was pretty printed, so I added some functions to break up that one for writing POST requests. Changed the output format a bit too, so it would be a bit more readable/standard looking. Seems to be working from my app, and fixed up the tests that had to change for this.

Not sure why there are so many commits listed. Seems like a lot of the ones from the last PR.

IMHO, I think it would be better to create an enum to represent print mode instead of using two combinations of 2 boolean flags. For example,

  enum class PrintMode {
    NORMAL,
    ONELINE,
    PRETTY;
  }

and in requestQueryString() would be

   fun requestQueryString() = document.operation.print(PrintMode.ONELINE, 0)

Would it be better?

[foxfriends]

Yeah that sounds like a better idea. I'll figure out a way to make it work. Maybe NORMAL, PRETTY and JSON?

[foxfriends]

Alright it is changed. Rewrote the tests a lot too, so that there would be less stuff that gets duplicated. Doubt there would be another print format but if there is it should be easier to write tests for now.

[VerachadW]

Please add a note here that requestVariableString() always return null for now. We will implement this after we support the variable.

LGTM. Thanks again for your help
