Code to parse UCI moves about nibbler

[rooklift]

Allowing UCI moves seems like it should be simple, except I think there's the following complication:

• Internally Nibbler uses Chess960 format for castling, e.g. e1h1
• So moves like e1g1 would have to be converted to e1h1
• But only if there's a king on e1 (because some other piece could move from e1 to g1)
• But if it's actually a Chess960 game then e1g1 could be the correct castling move after all

Still, I'm thinking about it...

Well, hopefully this commit adds what you're looking for. I already had the code to deal with the C960 issue, I had just forgotten about it... :)

OK, initial tests suggest there's some bug in that code. Looking into it...

Edit: Nevermind, there probably isn't.

Wow! Awesome response time. I was under the impression Nibbler was no longer being maintained after reading some exchanges in other threads.

This is an awesome program and thank you!

It's true, I barely maintain it. But this was simple enough and it's actually something I had wanted in the past at some point.
