Warn on overwriting?

[unhammer]

It'd be nice if this could warn before overwriting existing files.

Thanks for the suggestion @unhammer. I agree that is an important thing.

I'd welcome a PR for this. Otherwise I'll try to figure out how to do it when I get some free time to work on this project.

I actually did this in my fork ( unhammer@010682b ), but I ended up changing the code style quite a bit (my laptop has a short monitor and I prefer seeing full functions in one screenful =P). I also swapped default to JPG 1600x1600, but if you want I can make a PR with your defaults?

(Also, would be nice if GIMP could remember the last used settings, other filters do this so should be possible?)

[per1234]

I'd be receptive to an improvement in the code style if it's in a separate, dedicated commit that doesn't make any functional changes.
