TreeItem should support highlights

[jrieken]

It would be nice if the tree view supports some kind of highlights in its label. This would be helpful when showing search-result-like things. Maybe something like this

export class TreeItem {

  label?: string;

  // start, end tuples
  labelHighlights?:[number,number][]
}

or something more elaborated that allows to reference a theme color or allows to express the highlighting style (background color or bold text etc)

@jrieken How about

export class TreeItem {

  label?: string | {label: string, highlights?:[number,number][]};

}

This will avoid providing highlights without giving label.

yeah, much better. it will give us a place to refer to the style
