Problems:
1. Using JE.Call to construct a JsonP response object results in a JsonResponse. It should be a JavascriptResponse as JsonP is a method call.

2. The existing JavascriptResponse object returns the content type of "text/javascript". RFC 4329 (http://www.rfc-editor.org/rfc/rfc4329.txt) recommends using
"application/javascript" as 'Use of the "text" top-level type for this kind of content is known to be problematic

Proposed solution:
1. RestHelper should implicitly convert JsExp into JavascriptResponses.
See https://github.com/lift/framework/blob/master/web/webkit/src/main/scala/net/liftweb/http/rest/RestHelper.scala#L611

2. JavascriptResponses should return the Content-Type of "application/javascript" (instead of text/javascript)
See https://github.com/lift/framework/blob/master/web/webkit/src/main/scala/net/liftweb/http/LiftResponse.scala#L263

Cheers!
