#965 - Added ENUM
Fixes #967

(cherry picked from commit 7618faba51d62edf17b33abbbd3144aa056528cd)
#592, #631 - Renamed antisamy file to avoid thymeleaf error when antisamy kicks in and allow for error msg to bubble up to the admin.
#592, #631 - Allowed span to have empty tags since redactor defaults to empty span tags sometimes.
#592, #631 - Turn off antisamy by default.
#967 - Fixed typo.   Ensure that default tracker does not use a name.
#974 - Don't allow the MapFieldPersistenceProvider to run if the RuleFieldPersistenceProvider has already run (avoids overriding dirty state detection)
#976 - Address ordering of property file consumption such that implementation shared and regular property files are last, behind any external property override file.
Fixes #980 - Do not utilize a repackaged version of the Jpa2PersistenceUnitInfoDecorator as some classloaders might not load it appropriately
