Coding style

[dreua]

Reviewing the latest pull request, I noticed (agian) that the code is a bit messy, the placement of braces and parentheses is unusual (at least to my eyes) and inconsistent throughout the project. I'd like to clean that up a bit to ease further development and maintenance.
@cnlohr do you have a preferred coding style for your projects?

A full run of clang-format changes almost every line, I'm not sure that is what we want. I could probably create a .clang-format configuration changing just the stuff that is annoying me the most, would that be a good idea?

Update: I read (in context of Python's "black" formatting) somewhere that it's possible to exclude commits from "git blame" and such, that would be a good idea for any automated formatting. Still not sure we want the full auto-format.

I have a personal coding style preference, but I usually try to keep the coding style whatever it was from where it came, or to match the coding style that is within locally. IN GENERAL, my PREFERENCES are:

• Tabs, not spaces.
• Spacing is:

if( ( x == y ) )
{
	printf( "hello, world!\n" );
}

• Hungarian notation fine. But not required.

It's basically the StepMania style, which coincidentally happened to be almost identical to the Valve style. (Except that Valve uses fl for floats and doubles as a prefix).

Do you have recommendations. I'm ok with smaller changes, but I don't like sweeping changes. Specifically because of the git blame issues. If you guys know a way of updating style or have feelings, let me know!

Also, @dreua you should totally bring this up in the Discord.

Sam E comments that we have one we have discussed: https://github.com/cnlohr/colorchord/blob/master/.clang-format

Also, I would be willing to do a nuke it and move it if you wanted to.
