when a graphic symbol is selected in the TextSymbolizer dialog, set symbolizer.graphic to true. Also update real-time on every change of the point symbolizer dialog. This is needed now that https://github.com/openlayers/openlayers/pull/372 set the default of graphic to false (see #SUITE-1550)
make sure url field shows the first time (see #SUITE-1549)
more fixes in graphic part of text symbolizer (see #SUITE-1549)

only show add button if catalogue record is associated with a WMS
