Add an "ignore fuel up" feature

[MD1032]

Thanks for the suggestion, pb, I guess I'll do that...after all, it's for informational purposes only. I searched the forum but I couldn't find anything on this. I guess I didn't look hard enough.

Matrix, I realize that this is a fuel tracking website, but not everyone really cares all that much about the statistics. Personally, I just use this as a fancy logbook, and if I can find a way to put as much information in it as possible, that makes it better. Besides, like pb said, if people don't want a crappy tank to be part of their mileage, they're just going to skip entering it altogether.
