load WMS without getFeatureInfo-Request is not possible

[astrid_emde]

Mapbender expects a WMS to offer getFeatureInfo-Request. The WMS Standard defines getFeatureInfo-Request as optional. Therefore Mapbender should handle getFeatureInfo as optional too.

there two NOT NULL constraints:

• wms.wms_getfeatureinfo
• gui.gui_wms_featureinfoformat

They avoid, that a WMS without the support for Request GetFeatureInfo can be loaded.

ALTER TABLE wms ALTER COLUMN wms_getfeatureinfo DROP NOT NULL;

ALTER TABLE gui ALTER COLUMN gui_wms_featureinfoformat DROP NOT NULL;
