Sparkle closes on program close

Sparkle should behave in a more modal manner, prompting the user to
cancel the update or cancel closing the main application if the main
program was closed.

1. I close the program, forgetting Sparkle has downloaded an update
2. Sparkle comes to front, asking if I'm sure I want to close and offering the option to continue updating or close the program.

This affects all applications that use Sparkle, and has been highly
annoying to me.

We'll fix it by resuming/reusing downloaded update #957 #71

You can think of this as a different issue. My fork always installs an update if it has been downloaded & extracted, for instance, even if the user terminates the app without hitting "Install & Relaunch"
