MMToolbar[Button] reimplementation

[PeterPetrik]

• broken MMMapController > MMMenuDrawer (@tomasMizera please replace with MMListDrawer in your PR)
• missing "Active" green label in MMListDrawer (@tomasMizera please add to MMListDrawer in your PR)

visually it is the same, just cleared the logic and improved API

usage (detto for long buttons and selectable buttons)

  MMToolbar {
    model: ObjectModel {
      MMToolbarButton { text: "Delete"; iconSource: __style.deleteIcon; onClicked: console.log("tapped "+text) }
      MMToolbarButton { text: "Edit Geometry"; iconSource: __style.editIcon; onClicked: console.log("tapped "+text) }
      MMToolbarButton { text: "Save"; iconSource: __style.doneCircleIcon; onClicked: console.log("tapped "+text) }
    }
  }
