[MPlayer-dev-eng] Documentation updates - surround etc

[Stephen Davies]

Hi,

Attached some documentation updates:

 - A paragraph on the surround plugin
 - A credit to Jake Janovetz, author of the LGPL remez.c used in
   pl_surround to calculate filter coefficients
 - Took the liberty to include a credit to myself ;-)
   [will a credit for mplayer help me get work, or lose me my job? ;-)]

Steve
