RFC: Extend skin engine to handle EQ settings

EQ settings are actually an array of 3 ints.  I added a skin parameter
token that allows specifying which array element to use.

So instead of this now-incorrect syntax:

   %St(0,0,-,-,image,eqbar.bmp,vertical,setting,eq band 1 gain)

You would use:

   %St(0,0,-,-,image,eqbar.bmp,vertical,soffset,2,setting,eq peak filter 1)

(the 'gain' is the third element in the eq setting array, thus soffset 2)
