Don't de-indent case and default statements

[yeldarby]

This commit changes the formatting of a switch statement from

switch(x) {
case 1:
    //stuff
case 2:
    //stuff
default:
    //stuff
}

to

switch(x) {
    case 1:
        //stuff
    case 2:
        //stuff
    default:
        //stuff
}

Note the indentation is not decreased for case and default statements.

I know others will likely disagree with this style preference but I couldn't figure out how to control this at runtime in my init script or keymap file.

Is there a way to add this change at runtime or add a preference so I wouldn't have to maintain a fork and keep it up to date with upstream changes?

Personally, I like the "classic" indentation behavior suggested in this PR as well 👍. Also, I've checked a few "major" JavaScript projects and those seem to use this way of indenting case as well.

(It seems that the current style of indenting case statements comes from [Crockford](http://javascript.crockford.com/code.html#switch statement): "Each case is aligned with the switch. This avoids over-indentation. A case label is not a statement, and should not be indented like one.")

Also, this fixes #33 I believe.

Well, that makes three of us that don't like case and default indented! Thanks, @yeldarby!

I know this is closed, just wondering if there a setting to modify it so existing projects that have been using the previous way don't have to reformat?
