msInsertLayer does not set the layer index properly

[szekerest]

insertLayer does not set the layer index properly if the layer is inserted
between the existing layers.

mapobject.c line 520
/* copy new layer to specified index */
        freeLayer(&(map->layers[nIndex]));
        initLayer(&(map->layers[nIndex]), map);
        msCopyLayer(&(map->layers[nIndex]), layer);
        map->layers[map->numlayers].index = nIndex;

the last line should be replaced with:

map->layers[nIndex].index = nIndex;
