Bug in parsing of "request" and "data" rules

[tsandall]

Rules with the name "request" and "data" may be defined for test purposes to mock out the normal request/data documents. The parser currently does not recognize expressions of the form "request = term" or "data = term" as rules.

ParseRuleFromBody should be updated to handle the "request" and "data" refs.

Example:

package ex

request = {"foo":1,"bar":2}

or

package ex

data = {"foo": 1, "data": 2}

A simple workaround is to declare the rule body, e.g., request = {"foo": 1} :- true.
