Can disallow properties

Naming is hard, so that's why this Disallowed Calls extension now supports disallowing instance and static properties, and enum properties with disallowProperties (#378)

Other (mostly) internal changes

• Add generics to Generator (#372)
• Handle all the include types in the switch (#373)
• Upgrade Dead Code Detector (#375, thanks @janedbal)
• Make the disallowedSuperglobals docs more clear that it doesn't recommend $_REQUEST (#377)

Oh, a Friday 13th release! 👻
