Patch: Warn users of APWorld version mismatch before patching

[snowflav-goob]

What is this fixing or adding?

Adds an explicit warning for users if the game they're playing has a different APWorld than the one used for generation. I've noticed that the errors that follow in that situation can often leave users confused, especially when APWorlds change their patching procedures, so I'm hoping to mitigate that.

How was this tested?

Generated a multiworld with Pokemon Crystal 5.3.5, patched, then downgraded to 5.3.0 and patched again

If this makes graphical changes, please attach screenshots.

is this wanted? I don't have a proper Patch game myself, but I don't believe that every game with one is changing the format every version, meaning this would cause needless worry with extra warnings.
rather this functionality might be more well placed into a mixin on the patch class that a world could opt into and potentially even tweak (i.e. ignore the final version digit when comparing)
