Title: Qt Tabbed List Editor Styles

This PR adds a minimal set of support for the `dock_style` trait of `ListEditor`s under Qt. In particular:

* if the dock style is set to `tab` then document-style tabs are used (which is most noticeable on OS X)
* if the dock style is set to `vertical` then the tabs are rendered with the `West` Qt `QTabPosition`
