"clear stage" button does not work

The "clear stage" button currently has text beside it (not actually very close by) saying "Clears the text chat and drawing layers." and when you click on the button you get a message saying "Warning: This will cause the stage to reload for everyone currently on it, and you will loose the chat log. Do you wish to proceed?"

In fact when you click on the button nothing at all happens - the stage does not reload, and even after a manual reload the chat and drawing are still there.

The button needs to be fixed so that it does indeed clear the chat & drawing; I'm not sure that an automatic reload is necessary though - I will ask Vicki what she thinks about that.

The text can be removed from the page & the pop up message should say:
"Warning: This will clear the chat log and any drawings from the stage. Do you wish to proceed?"

(or if we decide an automatic reload is the right then then it should say "Warning: This will clear the chat log and any drawings from the stage, and the stage will reload for all players and audience on it. Do you wish to proceed?")
