Replaces the old Gradle plugin with plain Gradle buildscripts. Also cleans-up
the current Gradle extensions and re-adds detekt, along with JUnit 5 support to
all modules.
Updates the testing infrastructure to use the latest relesae of junit and
leverages the new extension mechanism to create an easy to use testing
framework. Also adds additional test coverage for several plugins.
Adds named arguments to enum declarations along with lookup functions, fixes
continuation indent, and replaces Map<Player, ArrayList<Prayer>> with a
SetMultimap<Player, Prayer>.
