Room identification label

We need players to have an idea of what room they are in. So each room needs a label (or title or something).
I have this working in accountEqn on my branch right now... We need to add this to all rooms and activities!

this.roomLabel = this.add.text(650, 6, "Account Equation Room", {
font: "24px arial",
color: "#FFFFFF",
align:'left',
fontWeight:'bold',
});
