[SERVER][BUGFIX] Layer order from group

rldhont · rldhont · commit ae906b5eca9f · 2015-09-15T16:42:47.000+02:00
If custom order is not enabled and a group is requested, layers was added in
 the DOM element order. The default endering order is the reverse.

To fix this issue, QgsWMSProjectParser::addLayersFromGroup has to read group
 element children from end (bottom) to start (top).
