Create replacements for legacy authors feeds (RSS, YAML)

[preaction]

The current site has a few APIs that allow authors to see their data via YAML, or to subscribe to recent reports via RSS. These feeds are advertised as orange buttons near the upper-right of the author's page (example author page for PREACTION).

For backwards compatibility, we should create these same feeds in this app. We should add a single method to CPAN::Testers::Web::Controller::Legacy called author_feeds. This method should return either an RSS or a YAML document based on the format requested (use $c->respond_to() to vary the responses).

There are two RSS feeds: One with all reports, one without PASS reports (called <author>-nopass.rss). A stash value ("nopass") should be used when wanting to filter the list of reports returned.

Once the controller action is written, and routes created, the Apache config will be updated to proxy to these replacements.
