bad "openfolder" kills the gui

[frankjaeger]

If the value of the element-var "openfolder" of treeGDE is bigger then the count of wms in the gui, than the gui can not load: no overview, no mapframe. This can happen, after some wms are removed from a gui. It is very difficult for the admin to find the reason. You can spend ours to find this element-var as the root of eval.

Please check on Load:

if openfolder > max-wms

then ignore openfolder

Alternatively check it on setting the value of the element-var and check it when removing a wms and when treeGDE is copied from an other gui.
