Add shift + left/right click actions and requirements to menus

Menu items can now configure on-shift-left-click, on-shift-right-click,
shift-left-click-requirements and shift-right-click-requirements.

When a shift click has nothing configured for it, it keeps falling back
to the regular left/right click actions and requirements, so existing
menu configs behave exactly as before.
