Patch enabling completion

Version:           SVN (using KDE 4.4.4) 
OS:                Linux

For this snippet of code, kdevelop4 does not provide me the list of names in
the boost::filesystem namespace:

#include <boost/filesystem.hpp>

namespace fs = boost::filesystem;

fs::path my_path; // hit ctrl+space after fs:: and nothing happens

The attached patch fixes it.

Also solved is the following valid C++ case (in the context of the above C++
scenario):

using namespace fs; // imports names from boost::filesystem


Reproducible: Always




When the completion list is formed, the algorithm only checks for declarations
of type Declaration::Namespace and adds their content to the list. My patch
adds a preprocessing on the declaration list by traversing
Declaration::NamespaceAlias declarations and resolving them towards the
imported namespaces.
