Python 2.7 used to return lists for operations such as map and range, this has changed in Python 3. To make the configs Python 3 compliant, add explicit conversions from iterators to lists where needed, replace xrange with range, and fix changes to exec syntax. This change doesn't fix import paths since that might require us to restructure the configs slightly.
