Merge branch 'standalone-executable-and-other-cli-cleanups' of https://github.com/meatballhat/resque-scheduler into meatballhat-standalone-executable-and-other-cli-cleanups
Handle $VERBOSE and $PATTERN in test runner

plus some other minor, seemingly unrelated garbage.
Switching to rake/testtask instead of home-grown thingy

as well as making the default rake task the same as what's used on
Travis.
