Display order problem in legend

[armin11]

The order of the sublayers of a group layer are reverse to the order of the layer in treegde module. Both orders can be configured - it has to be tested, if some element_vars may work as they should.

See:

https://github.com/mrmap-community/Mapbender2.8/blob/master/http/javascripts/mod_legendDiv.php

element_var: reverseLegend

and

https://github.com/mrmap-community/Mapbender2.8/blob/master/http/html/mod_treefolderPlain2019.php

element_var - reverse: true
