Title: Support for negative numbers

I forked your repository and modified it a little so that it could display negative numbers using a "minus" sign. I also made the negative sign move depending on how many digits are on the display.

I was thinking you may want to look at my modification and perhaps implement it into your code if it's acceptable. If not, that's okay too.

Note: I also changed the error message on the display for a digit overflow. That's more for aesthetic reasons for myself, so you may want to omit those changes.
