Integration with OSM wiki data items

[Don-vip]

We could use ​osmwiki:Data_items in several ways:

• validator:
  • automatic rules for wrong geometries (​osmwiki:Property:P33, ​osmwiki:Property:P34, ​osmwiki:Property:P35, ​osmwiki:Property:P36)
  • automatic rules for too small/too big buildings (#17846)
  • detect obsolete, deprecated, discardable values based on their status (​osmwiki:Property:P6)
  • validate values on their regex (​osmwiki:Property:P13)
  • detect missing tags (​osmwiki:Property:P22)
  • detect incompatible tags (​osmwiki:Property:P44)
• presets:
  • fetch and display image+caption in presets dialogs (​osmwiki:Property:P28, ​osmwiki:Property:47)
• UI:
  • go to data item page when right clicking a tag (properties dialog, relation editor, changeset dialog, history dialog...)
• plugins
  • tag2link:
    • ​osmwiki:Property:P8 could replace the internal config files
• more?

We could also document some JOSM features on the OSM wiki data items:

• define a "JOSM image" on the same model than "OSM Carto image" (​osmwiki:Property:P39)
