#927726 by catch, manarth: Fixed Clustered Varnish servers: varnish commands fail on the first failure.

#905980 by Ian Ward, fgm | cweagans: Fixed Notice: Undefined variable: output in varnish_admin_reports_page().

#859116 by fabsor, spearhead93 | rjbrown99: Fixed Varnish module, latest dev, gives 'Socket Error' with Varnish versions < 2.1 (needs documentation).

Also fix to .info file to put it in the "caching" package with the rest

Removing depricated "active_paths" function in favor of Expire module; calling out varnish_expire_cache() as the right function to integrate with

Adding proper http.host and base_path() respect for cache purges. This should now be multisite friendly.

Also removing the varnish cookie. This is just a bad idea.
