Alt click adds unit%2Fimprovement to top of system que, like science que currently has

It was in Es1, with lot of other good shortcuts.

I hope most of them implemented in Es2, but I think we won't see it until last updates or release.

And also a limilar option to move something to the bottom of the que. E.g. alt-clicking the first element in the que moving it to the bottom, or another ctrl-click. Should be useful for moving "industry>sience" and similar actions to the bottom after adding a long list of things to build (e.g. ships)
