Subject: [PATCH] feat(globe): answer the clear and share actions through the
 globe actions store

The top-center bar is now GlobeActions.vue. The shell publishes whether a
clear is under way and answers the clear and share buttons through the
globe actions store, instead of binding listeners and writing attributes on
the buttons. A shell disposed mid-clear resets the busy state, so the next
shell's bar is not left busy. bindClearLayersControl stays exported and is
deprecated.
