Add the ability to select cancel all after multiple sessions have been selected to be opened

On the initial launch of the application if it has been closed with sessions open you are prompted to have the sessions you have selected reopened. If you accidentally click ok and have multiple sessions selected which require credentials (in my case I've had 10 sessions) and you don't actually want to connect you have to select cancel each time or crash the application and reopen it. A cancel all button would be incredibly helpful since it would allow you to cancel all sessions at once.
