Also implemented a counter for playing time, which can pretty easily be used to determine the length of the file, in seconds, before playing it. The time isn't displayed anywhere right now, but all this can be useful if this thing is turned into a codec, or at least gets a nice UI. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@15418 a1c6a512-1295-4272-9138-f99709370657

Set sampling rate to 22k, and increased note decay time. Reduced number of concurrent active voices and made new notes replace used voices if none are available. This makes lag less apparent.

In revision 1.4 Steven made currentVoice global, so the function declaration should be: synthVoice(void), wich fixes a warning. And the call should be just synthVoice() wich fixes a hidden error.
