Things pushed to hex.pm:
Make sure to bump app version if the .app.src or .hrl file changes, even if no .erl files have changed.
make an annotated tag, so --follow-tags (git 2.4+) works
ensure exactly one \n at the end of rebar.config
strip trailing whitespace from rebar.config properly
ignore changed modules from ./apps/*/test and ./test/
version i've been using for irccloud stuff
