Sidebar Control

type Sidebar interface {
	Control

	AppendCategory(text string)
	DeleteCategory(index int)

	AppendItem(category int, name string)
	DeleteItem(category int, index int)

	Selection() (category int, index int)		// or Selected()?
	Select(category int, index int)

	OnSelected(func())
}

Simple two-level sidebars.

Could have images on each item in the future.
