msSaveMap() doesn't save TRANSPARENCY ALPHA properly

[dmorissette]

msSaveMap() currently writes "TRNASPARENCY 1000" instead of "TRANSPARENCY
ALPHA", a special case needs to be added for that in writeLayer().

While checking mapfile.c, I noticed that loadLayer() uses
"getIntegerOrSymbol(&(layer->transparency), 1, MS_GD_ALPHA)" but
loadLayerString() uses "getInteger(&(layer->transparency))". 

Steve, can you please confirm that they should both be using getIntegerOrSymbol()?

I'll take care of fixing this once I get confirmation from you Steve.

Sean added that support and he missed fixing loadLayerString(). So:

  1) both should use getIntegerOrSymbol()
  2) writeLayer() should write "TRANSPARENCY ALPHA"

Fixed in both 4.9 and 4.8.2
