Add basic support for gmx:Anchor

[fxp]

The following changes are required to add gmx:Anchor support in view mode and edit (existing Anchor).

• To use the gmx:Anchor (substitute of gco:CharacterString) for an element use the schema-suggestion configuration file:

	<field name="gmd:keyword">
		<suggest name="gco:CharacterString"/>
		<suggest name="gmx:Anchor"/>
	</field>

	<field name="gmx:Anchor">
		<suggest name="xlink:href"/>
	</field>

Restart the application.

• update-fixd-info : remove template which replace gmx:Anchor by gco:CharacterString.
• Add labels and description in loc files
• Avoid xlink resolution for gmx:Anchor
• Add hyperlink in view mode and open in new window
  • for keywords and other type of element
