Fixed version of PHP-Parser to 0.9.4

PHP-Parser 0.9.3 and before contained bugs that hindered the
execution of the Reflection Library while the versions above
0.9.4 have their class names namespaced, which hinders with the
way this library knows which element type was finished.

When using versions above 0.9.4 this library won't detect any
elements in the provided source code.
