Set up some standard extensions for Wikispore wikis:

• common wikitext syntax extentions:
  • ParserFunctions
  • Cite
  • TemplateStyles
• common user experience extensions:
  • Echo
  • Thanks
  • MobileFrontend
  • ULS
  • CodeEditor
  • CodeMirror
  • WikiEditor
  • maybe VisualEditor (nice for user experience but it means we'd have to set up Parsoid, maybe RESTBase, maybe Citoid; that tends to be a world of pain) (see T237819: Install VisualEditor and Citoid on Wikispore)
• extensions for integration with production
  • Interwiki
  • (GlobalUserPage - see T237770: GlobalUserPage should not require the global wiki to be in the same database cluster)
  • (OAuthAuthentication - see T231908: Integrate Wikispore with SUL)
  • (WikibaseClient - see T231897: Connect Wikispore to Wikidata)
• maybe Gadgets for customization
• ideally CirrusSearch for a decent search experience. Not sure how hard it is to set up the ElasticSearch cluster it needs.

See T231072#5434459 for further suggestions about some less basic things.
