[telepathy-qt4/master] shared-ptr: Added WeakPtr::toStrongRef that returns a SharedPtr from a WeakPtr.

[Andre Moreira Magalhaes (andrunko)]

Rationale (Jonathon Jongsma):
You also might consider something like the boost::weak_ptr::lock() API that
allows you to easily create a SharedPtr from a WeakPtr.

Added "lock" idea but using Qt idiom, as used in QWeakPointer.
