Summary	0003205: Re-work type system to not use 'mixed' types (on hold)
Description	Eliminate 'mixed' types being ever set explicitly. 'mixed' should only occur when doing type analysis and finding a conflict. Instead we will support union types. Union types will be carried with variables as an additional possibility than just a single type. The union type will never expand or switch-out, although a non-union type can become union if it has union assigned to it. Any use of 'mixed' in phpdoc should be replaced with union types. Any variable will be allowed to take a 'null' value. The mixed() function can be removed.
Additional Information	This will allow better robustness and removes the mixed() function which is currently used very inconsistently.
