Add canonifyurls config option.

Browse Source 
Be able to inhibit AbsURL canonicalization of content, on a site
configuration basis. Advantages of being able to inhibit this include
making it easier to rendering on other hostnames, and being able to
include resources on http or https depending on how this page was
retrieved, avoiding mixed-mode client complaints without adding latency
for plain http.

By default, all relative URLs encountered in the input will be canonicalized
using `baseurl`, so that a link `/css/foo.css` becomes
`http://yoursite.example.com/css/foo.css`.
Setting `canonifyurls` to `false` will prevent this canonicalization.
Benefits of canonicalization include fixing all URLs to be absolute, which may
aid with some parsing tasks. Note though that all real browsers handle this
client-side without issues.
Benefits of non-canonicalization include being able to have resource inclusion
be scheme-relative, so that http vs https can be decided based on how this
page was retrieved.
