skins.minerva.editor: Remove unused dependencies

We were not using some of the code this was depending on. No idea when
it stopped being required.

'skins.minerva.scripts' was used until recently (d27a9481, 72cd31f2),
but now its only purpose was to load other dependencies. Add them
separately instead.

Removed dependencies:
* mediawiki.ui.input
* skins.minerva.icons.images.scripts
* skins.minerva.scripts
* skins.minerva.toggling

Added dependencies:
* mediawiki.api
* mediawiki.storage
* mediawiki.user
* mobile.init
