Add support for CCSelect sound

["Guy L. Albertelli" <galberte@neo.lrun.com>]

While pawing through a native control relay trace for Listview, I saw that on a LButtonDown message selecting a item, the system
played a sound. Tracing back it is due to the Sounds Control Panel item "Select" which is stored in the registery under "CCSelect".
So I implemented it as a general interface for the common controls.
