[GN to GS] Option to use the technical name rather than the title name

[MaelREBOUX]

Would it be difficult to create an option that will pick the "technical name" of the layer on the metadata

/gmd:MD_Metadata/gmd:distributionInfo/gmd:MD_Distribution/gmd:transferOptions/gmd:MD_DigitalTransferOptions/gmd:onLine/gmd:CI_OnlineResource/gmd:name/gco:CharacterString

rather than the title name as currently ?

The cause : we have many many metadatas with long title (legacy) and we put a shorter and technical name on the WxS service description part.

Example :

• title legacy = Référentiel Métropolitain Topographique et Réseaux : objets de surface : clôture
• title technic = RMTR Surface : clôture

By this way, it is the technical name that is showed in Mapfishapp.
