Update Checker

[shaggytwodope]

Nice! How about either days or hours check? Checking once a day is enough to me.

This is relative, the current option is based in seconds. I'll try to figure out a "daily" option... maybe something that cancels out the seconds option. But you can still set the time in seconds per 24 hours. Which would be 86400 seconds. I personally think something in the range of 3600 is ok. There is room to improve all of this, as I have time I'll try to improve on any options. But remember I'm only one person, And I get nothing from my work but helping some people adopt Linux hopefully.

If Jerry wants to make a release soon for people to test (I need testers and info reported back to improve things) otherwise any dev work will be shared here. And the code is available on my github: https://github.com/shaggytwodope/lite-updater with no packaging or installer yet.
