Revision 2785

Wms-Extension: some fixes in order to make it work again.

* Extensions/wms/infodialog.py(calcText()): removed encode('latin1')
as the Title already should be in the internal Thuban encoding.

*  Extensions/wms/properties.py:  removed encode('latin1')
as the Title already should be in the internal Thuban encoding.
Added copyright year 2007. Fixed reference to wx.EVT_BUTTON.

* Extensions/wms/layer.py: Using internal_from_.unicode now to bring
 the layer title in the right encoding.


* Extensions/wms/wms.py: adapting call to draw_raster_layer as
draw_raster_layer() got the calling parameters changed in rev2618.
Changed the preset selection choice towards demo.intevation.org, as
the frida wms does not seem to work anymore these days.
Fixed reference to EVT_BUTTON (was probably an oversight from the wx2.6
migration.)
