Suggestion: Add a callback when diff is ready

[Tyf0x]

Hi,

In a project I'm working on, I need to automatically scroll to the first diff available and give the user the ability to navigate to previous/next diff.

The issue I'm facing is that there is no event or callback sent to tell when ace-diff is done computing and displaying the diffs.

I've read somewhere that there might be a diff navigation in the works, but in a short term could it be possible to expose a "ready" callback in the ace-diff api?

Cheers!
