KDevelop has huge problem locating classes that use namespaces:
- can't locate classes without full namespace path
- cat't locate class class with full namespace, if class definition isn't included.

for example:
file def.php:
----------------------------------
<?php

namespace Foo;

class Bar {
}

// works
$bar = new \Foo\Bar;

// not working
$bar = new Bar;

-----------------------------------

file use.php:
-----------------------------------
<?php

namespace Foo;

include 'def.php';


// not working without include above
$bar = new \Foo\Bar;

// not working
$bar = new Bar;
-----------------------------------


Reproducible: Always

Steps to Reproduce:
Just create files live above.

Actual Results:  
Class Bar is not found and no class help is available.

Expected Results:  
Class Bar should be located without any includes, just like classes without namespaces.
