#17 catch NPE from XBoundingBox

If a renderer/editor, which uses GeographicInformationPanel, is started with
DevelopmentTools.createRendererInFrameFromRMIConnectionOnLocalhost()
then a NPE is thrown in the constructor of XBoundingBox. This NPW is
caught in GeographicInformationPanel, such that the render can start
again.
 #17 changed size of a textarea in ResourceRenderer

In the resource renderer in the description tab, the textarea shrinks to
one row if the content is big.

If a resource is of type 'experiment result data' then its icon in the
title should show a 'X'

 #17 pretty text for Role and Topic tags

The tags have ugly names like pointOfContact. To make the text more
beautiful, bundles were created, which contain the ugly version as key
and the beautiful version as value. When a tag should be shown the
beautiful text can be loaded from the bundle.

 #17 Assumed wrong type for representation.spatialscale

property 'spatialscale' of a representation CidsBean is needed. As the
property is an Integer, but was casted to a String, this led to a
ClassCastException.

The field cidsBean in GeographicInformationPanel was renamed to
resourceCidsBean, to make it clear that the cidsBean is of type
Resource.
