Allow font choice

[Jmuccigr]

Thanks for this. I usually use LibreOffice for csv work, but it's having trouble today with some upgrade issue so I was looking for something lightweight.

It would be great to be able to change the font, ideally through preferences, but even a simple +/- to increase or decrease the size would be welcome. It's also a little odd (to me) that it uses a non-monospaced font.

(Optional) Monospaced font would be great

This would be a program-wide setting which we could implement in a preferences window.

A choice would be great, but as @kubisflo writes, monospaced would be a step forward in the meanwhile. That's pretty standard in plain-text viewers (Excel's stupid default aside).
