Colorama edit fixes (v2)

This builds off of #122 & #123.

Starting with #123, this makes two (simple) changes:
 - colorama needs to be initialized to work
 - `colorama.Fore.CYAN`, et al. are just shortcuts for the ANSI codes, which colorama then interprets. So we don't need separate coloring instructions for the two platforms

I've tested it on my end on Windows, and colored output and editing both now work.

Closes #121, closes #122, closes #123.
