Implement view-source protocol. Fixes #4181.

Browse source 
This follows the recommendation from issue #4181. A handler
for 'view-source' delegates to the HTTP loader. In that
loader I check for view-source, adjust the URL to be the
URL to be viewed and modify the Content-Type header to be
text/plain.

This doesn't actually result in the source being
viewed as rendering text/plain is not yet implemented.
