Changed default ScreenSelecStyle to use functions for choice names and positions instead of metrics. _fallback SSS remains the same for compatibility. Fixed style stomping bug in SetCompatibleStylesForPlayers.

+* [ScreenSelect] ChoiceNames can be a lua command that is evaluated to get a
+  list of the gamecommands.  The main use of this is to get rid of the huge
+  list of metrics that ScreenSelectStyle requires.  A single lua function
+  instead of a metric for every style for every game type. [kyzentun]
+* [ScreenSelectMaster] IconChoicePosFunction metric added.  This metric is
+  optional, if it's set, it must be set to a function that returns a table
+  of positions.  Each position is a table of the form "{x, y, z}", where x,
+  y, and z are numbers and any that is not a number defaults to 0.
+  The function is passed the number of choices for the screen.
+  IconChoiceOnCommand and IconChoiceOffCommand metrics added so each choice
+  doesn't require its own On/OffCommand pair.  These are also optional, but
+  if they are set, they will override the individual commands if they exist.
+  (If "IconChoiceCactusOnCommand" and "IconChoiceOnCommand" both exist,
+  "IconChoiceOnCommand" will be used.) [kyzentun]
+  Example:
+  # in metrics.ini
+  IconChoicePosFunction=choice_positions
+  -- In a file in Scripts/
+  function choice_positions(count)
+    local ret= {}
+    for i= 1, ret do ret[i]= {i*24, i*48} end
+    return ret
+  end

   See comments in _fallback/metrics.ini above the [ScreenGameplay]
   MarginFunction metric.  Basically, you can define a lua function that
   returns the space you want at the edges and in the center instead of
   setting position metrics.  Do NOT use Style:GetWidth to calculate the
-	margins your function returns.
-	ScreenGameplay now handles zooming the notefield to fit in the space

-	If the notefield doesn't fit in the space between the margins, and there is

   as an extra arg, and they can be chained.
