Added postJson and putJson to the Service wrapper prototype

[zipang]

The first thig that i tried.... create a service wrapper for a JSON API (which API is not JSON today?) and... bingo.. it was missing..!

I landed on the main page/documentation and encountered the issue as well.
It costed some investigation into restler source until later I found this bug.

Did you try my fork for that purpose ?

My current solution is a common class that extends restler to provide
postJson and putJson.
I intended to made a small contribution back, then I found this PR, so just
comment.
I think this fix worths a review/merge, rather than a fork, in order to fix
the "first impression". The restler documentation shows an example of
postJson that does not exist.

Could you update the docs to list the support of this method?

Can you add a simple test for coverage?

Thanks 🍭
