Raspberry Pi Restarts After MightHat Shutdown

[Felix]

Guys, i've spent this evening debugging this issue and I was able to replicate. The hardware does not really have a problem. It's a software issue. Specifically the latching behavior is probable a little more sensitive than I expected.
I updated the MightyHat sketch with some changes from dmaxwell which I should have included when I added the buttons, and also I made more changes to the power latching.
Please try the latest sources and let me know if there's still an issue.

My MightyHat with LCD is working fine now.  I've shutdown and restarted several times with no problem.

Thanks for the fast support.  I'm enjoying this equipment, especially the ability to customize and reconfigure to my own taste and situation.

Thanks for the feedback, glad it works now.
I added some more tweaks.
Generally I keep on tweaking the code as I run into any issues or something that bugs me. So a good idea to check for changes.
