Description of the Issue

When I start Notepad++ and there is an upgrade available, it would be nice to have the option to upgrade on exit rather than now. I load Notepad++ because I want to use it, and I'd prefer to be able to delay the upgrade until I'm done my task.

Steps to Reproduce the Issue

1. Launch Notepad++ when there is an upgrade available
2. Receive dialog box that an upgrade is available, would I like to upgrade now or not?

Expected Behavior

1. Launch Notepad++ when there is an upgrade available
2. Receive dialog box that an upgrade is available, would I like to upgrade now, when I exit, or not at all?

Actual Behavior

Current dialog box has two options, upgrade now or cancel.

Debug Information

n/a

Other

Paint.net has the feature to upgrade on exit, and I'm always happy when I can say "yes, upgrade, but don't bug me about it right now"
