Review request for KDevelop.


Description
-------

Fix the support for PHP 5.3's late static binding so that the 'static' keyword in

return static::property;

or

return static()

maps to the class it was declared in.

This is not 100% correct behavior, but since static is evaluated at runtime we can not determine at parsing what class type it really is.
However, it's always gonna be either the class it was declared in or one that extends the class it was declared in, so using that class as type should
provide better information than for example mixed.


This addresses bug 278085.
