Changes:
* Minerva now maintains a MinervaUI - a simplified version of
MobileUI that provides iconClass and buttonClass helpers.
* Minerva now maintains its own ResourceLoaderParserMessageModule
Remaining issues:
* Main menu links to '#'
* Unknown dependency errors are thrown due to the missing
JS libraries e.g. mobile.watchstar
thus JS based UI components are unusable e.g. search autocomplete,
and edit button
* Language button navigates to a missing special page without
MobileFrontend (see T104660)
