hgweb: add a `web.view` to control filtering

This options add a new `web.view` to control filter level of hgweb.

This option have two purposes:

1) Allow fall back to unfiltered version in case a yet undetected by critical
   bug is found in filtering after 2.5 release

2) People use hgweb as a local repoviewer. When they have secret changesets,
   they wants to use "visible" filter not "served"

(modified by mpm, documentation deferred)
