PLEASE ADD MEDIA TYPE AS A PROPERTY OF REST REQUEST STEP

1. One goal for our product is to support both xml and json format in all REST APIs, so I have to test all APIs by using both application/xml and application/json as media type

2. From time to time, I have to read/modify the contents of REST request/response by using groovy scripts.

3. The current issue is that the media type is only shown on ReadyAPI test step review/edit screen. I can neither find it in properties of the test step, nor find any method of testStep object to get it.
