Feature Request: Change thickness of gutter decoration

[almic]

On my monitor, the gutter lines a very thin. I'm using minimap-git-diff and went digging through the settings and code to figure out how to change the line thickness. Turns out, gutter decorations are hard-coded to be 1px wide. And on a 1080p monitor that is pretty thin.

It would be nice if you added a setting to change that, or made it relative to screen size (not sure if that's possible.)

I would change it myself, but I don't know how, and I don't want to spend the afternoon learning all about coffee script and atom package structure to do what someone else likely could spend 1 minute adding.
