Allow customizing `ActionBar` overflow menu label, or default to "More items"

[iansan5653]

The label for the ActionBar overflow menu is forced to be More {menuLabel} items. This means that for any well-formed, semantic label for the action bar, the overflow menu is going to have a nonsense label/tooltip.

For example, logical names for the toolbar include "Formatting tools", "Issue actions", "Repository navigation", etc. The resulting overflow menu names for these are "More Formatting tools items", "More Issue actions items", "More Repository navigation items". They all have bad capitalization, are long for a button label, and most just don't make sense with two plural nouns.

I think one easy solution would just be to just change the label to "More items". This is generic, but should be fine because it's always nested inside a labeled toolbar, so it's clear based on context what it's referring to. It works in every context and is succinct and clear.
