Through the SetExternalPlayer() method and the ExternalPlayer property
is possible to associate an arbitrary executable to the "external player"
button (for clearness see http://www.sopcast.com/docs/ where the player
control buttons are showed) which opens Windows Media Player by default.
When the user click this button, the executable is launched without prompts
Also this value is stored in config.xml, inside the sopcast local folder
for further use, ex. with the sopcast client application
Note: this control is safe for scripting and safe for initialization
