make it easier to see object ids

[dieterdreist]

I think there would be space somewhere to show the object ids, right now if an object has a name the id is not so visible.

E.g. in the selection window, the ID could be shown after the name (in the regular non-bold font, to distinguish it).

Also in the title bar of the tags window, it could be added

Quite important it would also be in the upload window.
