Don't set referrers on outgoing plugin requests if the load_manually flag is set. This emulates the
behavior of other browsers and fixes http://code.google.com/p/chromium/issues/detail?id=28800

I added a UI test to validate that the plugin source URL is set on outgoing GetURL requests issued
by the plugin. To validate that the document URL is set as the referrer on the initial URL request
would take some more work. Will try and add that in a future CL.

I also changed the WebPluginImpl::RouteToFrame function to set the referrer on similar lines.

lgtm

can we write a test for this?  perhaps with the npapi_test_plugin in an iframe
and it signals to the parent page that it got the correct header?

I added a ui test to validate that the plugin source URL is set as the referrer
for outgoing URL requests issued by the plugin. Will think about the test for
the document URL as the referrer and add that in a subsequent CL.
