Add an initial .travis.yml.

Since kilium is now public, setup travis to verify it.  Thus add an initial
.travis.yml file.  Notably, it uses coveralls to keep an eye on test coverage,
and falls back to normal go testing if the coveralls token is unavailable.  IT
uses an external script due to limitations of travis.
Due to some missing commits in go-pkg-rss, use my own package.

Due to some missing bugfixes in go-pkg-rss, use my own local copy instead of
the default upstream version.  This should fix all build failures.
Fix test suite to work with latest github.com/gorilla/feeds.

The feeds package no longer outputs seconds into the generated RSS feeds.
Due to this, seconds can no longer be checked.  To fix for now, simple kill
any seconds in the test data that is used for RSS parsing.  This means the
seconds are no longer tested, but it shouldn't be too much of an issue.
