output valid WMC documents

[tomkralidis]

If I:

• go to ​http://www.fao.org/geonetwork/srv/en/main.home
• click "Open Map Viewer"
• save context document

...the resulting WMC doc is invalid. Below is what would constitute a valid output (tested in XMLSpy 2008).

</ViewContext>

Note that the main changes are:

• root element schema addition
• ViewContext/General re-ordering of elements (Window, then BoundingBox, then Title)
• ViewContext/LayerList/Layer re-ordering of elements (Server is always first)

If no markers included the generated WMC validates, but if markers are included the Extension definition in context.xsd have to change to

<xs:any namespace="##any" processContents="lax"/>

actual is

<xs:any namespace="##any"/>

to validate correctly.
