switch to https for rubygems
fix broken info tests

prevent future breakage by relying on testcasks instead of live ones
kill homebrew submodule; call out to system one
basic tests around edit
parens to fix syntastic warning

feature
create casks with `brew cask edit foo --create`
add surplus-meter cask
add skitch cask
seeing if we can get travis to work
use bundle exec for travis

and be explicit about task
a quixotic journey to a passing travis build
