Universal code formatting rules

[andrast0th]

I've worked on this code from 2 IDE's and 3 computers. It's a bit of a pain to see inconsistent formatting in all the diffs.

I would like to improve it, but I'm not sure how.
Is there any universal code formatter we can use, something that works consistently with both IntelliJ and Eclipse.
Or adding some formatter as a pre-commit hook?

@slbruce Any ideas?
