plugging moar leaks

Namespace Leaks: these leaks would have been freed on app kill but they were still contaminating the log so free em.
Con::shutdown: gGlobablVars again another leak that would of been freed on app kill
AssetManager onRemove should be clearing its lists
Scripting language needs a free for its strings these destructors free after the rule is executed so the data is cached internally and then freed. This may be needed for other types in the union (should not be used on nodes just raw data)
