[Fiware-miwi] webui standards page

[Toni Alatalo]

one of the APs in the meet was to add information about us & standards
in the fiware wiki.

i created a stub with a little beginning for it now:
https://forge.fi-ware.org/plugins/mediawiki/wiki/fiware/index.php/Mapping_Advanced_Web_User_Interface

linked it from https://forge.fi-ware.org/plugins/mediawiki/wiki/fiware/index.php/Standardization_Activities
where you can see the other parts for examples for how we should add
these things.
