Improved type detection for object properties.
This should solve long standing bugs that make kdev-php difficult
to use with common PHP frameworks.
- Properly resolve namespaced identifiers for type information in the phpdoc block
- Default type for class properties without assigned value is now NULL instead of 'mixed' (if no other type is specified in the phpdoc block)
- The NULL type is replaced on first assignment to the property.
