Automatic Update Checker

[Drewsif]

Hello all! I wanted to do a quick poll to see how people felt about automatic update checkers in PiShrink. I have an implementation that reaches out to Github to check for a version mismatch on the release versions and displays a warning if it is out of date.

I set a short timeout (5 seconds) to not make it painful to use without internet but wanted some feedback on the feature. So please let me know what you think!
