Ordering monitors

[ljuzig]

Is there any way to set the order of the monitors on the top bar? I was used to iStat menus on macos having CPU on far right, then Ram, Disk e finally Network. I couldn't find a way to reorder them.

Forked the repo and added a simple option to invert the order of the monitors.

If it is a welcome addition to the project I can create a pull request.

I also organized the settings panel into categories, I plan to add a little more display options if I can.

Thanks! I've been wanting to clean up the preferences like this too. I'm out on baby bonding leave right now so haven't had a chance to review this, but wanted to say I really like the look of what you've done. My only comment right now is could we use the same icons in the Preferences window as TopHat uses in the top bar?
