Clean message text

Send a message to another user using the messaging interface (user menu > messages) Confirm that sending script tags doesn't run the javascript on the page, e.g. sending <script>alert('test');</script> doesn't popup an alert (sending a message with only <script> tags will result in an empty message being rendered in the message area) Confirm that you can send html messages, e.g. <strong>test message</strong> should display the text "test message" in bold Confirm that the last message under the user name in the panel on the left is updated to plain text and doesn't have any HTML tags, e.g. in the script test above that text would say "alert('test');". Confirm that the last message in the message popover in the nav bar is displayed in plain text and doesn't have any HTML tags (assuming the last message had HTML tags). The popover should not error when opened. Note: unlike the last message in the messages panel the popover isn't updated dynamically as the user types, so you'll need to reload the page to have the last message updated. Confirm that the message timestamp is shown on a new line (bottom right) of the message, not inline with the text, when you send HTML messages (check this on clean and boost themes).
