Add boolean conversion in request types

Entering in boolean expression like $request->setRecord(true) does not automatically convert to $request->setRecord('true')

Yeah, I asked Shannon to make an issue so we don't forget it. I think there may have been a BC break that caused this, but it's impossible to tell.
