proxy mode support readded!
- use wsgiprox wrapper in FrontEndApp.init_proxy() with fixed collection prefix, ca options
- cli --proxy <coll> flag added to specify proxy collection
- cleanup: remove cookie rw (already disabled), fix post handling paths
- headers: ensure request headers are not rewritten when in proxy mode, response headers marked with 'url-rewrite' also no rewritten if no url rewrite/proxy mode
- urlrewriter: add IdentityRewriter with no rewriting as default, instead of SchemeOnlyUrlRewriter
- memento support: for now, only include rel="original" and Memento-Datetime in for proxy replay response
- responseloader: disable urllib3 unsecure response warnings
- tests: add test for proxy replay and proxy record/replay of new collection
rename tests to test_proxy_https_cookie, test_proxy_http_cookie, test_proxy_http_auth
to allow for testing, http proxy, cookie resolver, proxy auth and https support in a more
orthogonal way
rename configs to test_config_proxy_http and test_config_proxy_https
will run (this was cumbersome to maintain and not really useful)
ReferRedirect just checks that the current request host header, if present, matches that of the referrer
and checks that the coll and script name match.
* removed proxy_pac as it was also unneeded/unused and required use of the hostpaths
* added test for invalid CONNECT usage (405 response)
