classitem variable substitution

[Steve Lime]

If you want to replace the whole item name you could do something like:

  map_elevation_classitem=xxxx

with the same effect.

Goodness bless open source.

mapserv.c after line 1615 (MapServer version 4.6.1)

added

if(map->layers[j].classitem && (strstr(map->layers[j].classitem, tmpstr) !=
NULL)) map->layers[j].classitem = gsub(map->layers[j].classitem, tmpstr,
msObj->request->ParamValues[i]);

It didn't seem to break anything and DID seem to work!
