Message:

Vector<UString> makes many needless calls to UString::UString and UString::~UString

Reviewed by Anders Carlsson.

Add a VectorTrait<UString> specialisation to allow vector to simply memset/memcpy
data around. Only difference from the VectorTrait<RefPtr<T> > traits is the inability
to use memset to initialize data.
