Add ability to specify dock layout, independent of the tray layout

doing this will provide the ability to design more flexible layouts

<Tray layout="vertical"
<Dock layout="horizontal">
</Tray>

If that is added, it would probably also need "wrap-width" and "wrap-height" to keep icons from getting so squished, that they become unrecognizable.

Legend: [&] = icon, Bottom is a simulated "Dock"

Wrap Example |-----------------| |[&] Menu | |[&] Show Desk| |===========| |[&][&][&][&][&] [&][&][&][&][&]|

No Wrap |-----------------| |[&] Menu | |[&] Show Desk| |===========| |[&][&][&][&][&][&][&][&][&][&][&]|

These icons would either get squished or the tray would grow to cover to much of the screen.

I agree maybe even the ability for the icons to slide under other icons when they run out of tray space horizontally, kind of like a grid
