Chat Pop-up Notification and Sound in Host Interface

Feature: Add an audible sound notification and 'toaster' pop-up notification in browser when a chat message is received while logged into the ScreenConnect host user interface.

Currently, a sound indicating a received chat message is played only when an active support session window is open.

No sound or notification pop up is displayed or made when a chat message is received when logged into the host interface. Only a small green dot is displayed to indicate a received chat message. It is very easy to miss a received chat message without having a support session open to a given user.
