Differentiate changed line icon for whitespace only changes

[etler]

When reformatting files, it can be a little confusing figuring out what lines have significant changes when there are major whitespace changes. Having a different icon for whitespace only changes would be very helpful in those cases.

Is this a feature that would be worth supporting in GitGutter? Also, what should the icon be? An unfilled outline of a square would probably be the most obvious.

@etler, I don't think this is something that I care to work on myself, I rarely make significantly white space only changes enough to ever care. However, if someone proposed a clean solution that could be off by default and turned on via settings, I would probably merge it.

Cool, I think I'll take a stab at it. I just wanted to check if there was interest in it so my effort wouldn't go to waste.

Also, before you spend any effort, it might be worth checking to see if this setting helps you.

Nice, thanks for pointing that out!
