Change in REST API

Hi,

I have made some changes in REST API.
I give you the source (it is a zip file renamed with txt suffix).

Thanks for the code. Better to have it as a GIT pull-request instead. But I'll be implementing the required behaviour today (comments based on process-instance through REST), so no need to create a pull-request for this one.
