Add a button to close the chat window

[alechaye]

Describe the problem

If you open the chat window, the only way to close it is by pressing the same button that was used to open it. It is not intuitive for an end user.

Describe the proposed solution

Adding a 'X' button or '->' to signal that you can close the chat by pressing there will greatly improve UI experience.

Alternatives considered

Adding the button.
