Title: Fix #18: Use unzip on Cedar-14 stack, else fallback to jar

The new cedar-14 stack now has `unzip`. We were depending on `jar` to unzip files, which is not available on the newer stack.

This fix supports both older `cedar` stack and the newer `cedar-14` stack (which is the default Heroku stack for new apps).
