Started importing "collections" from "collections.abc" under Python 3.3 and greater for Python 3.8 compatibility. Pull request courtesy Nathaniel Knight. In Python 3.3, the abstract base classes (Iterable, Mapping, etc.) were moved from the `collections` module and put in the `collections.abc` module. They remain in the `collections` module for backwards compatibility, and will until Python 3.8. This commit adds a variable (`collections_abc`) to the `util/compat` module, which will be the `collections` module for Python < 3.3 and before, or the `collections.abc` module for Python >= 3.3. It also uses the new variable, getting rid of some deprecation warnings that were seen when running under Python 3.7.
