To avoid confusion in control names for the standard analog PC Beep generator using a small Internal PC Speaker, rename all related "PC Speaker" and "PC Beep" controls to "Beep" only. This name is more universal and can be also used on more platforms without confusion. Introduce also "Internal Speaker" in ControlNames.txt for systems with full-featured build-in internal speaker.
