Allow <ESC> to close OK-style dialogs, enclose task names in quotes

Please allow the <ESC> key to close "information/msgbox" dialogs that have just one "OK" button, as that's the usability convention.

Also, the task name will look better if "bolded" or on a separate line - please see the screenshot. Otherwise, it looks "funny" in some cases and it's not clear what the name was - it blends with the rest of the message box text.
