Provide means to relocate component in the tree through <TreeName>

We should provide a way to 'move' a component in the visual tree without having to change it's id.

Use Case

It's sometimes desired to restructure the visual installation tree. However, because the <Name> of a component both serves as the component's id and as a hint to the installer where to show the component tree this is hard to do.

What you can do is giving the component a new <Name/>, and mark it as a replacement with the <Replaces/> tag. However, this is not very-well-tested, and a potential problem.

Idea

Provide an optional <TreeName> element in package.xml that will be used together with <SortingPriority> to define where in the component tree a component will be shown.

If <TreeName> is not specified it falls back to <Name>.
