Optional command color

[avi-cenna]

Draft MR which attempts to resolve #1186, ie allowing for colored command output. I can add to the list of available colors, but was hoping to get a quick review first to make sure my approach is sensible.

@frederikhors Do you mind doing a quick review of this draft MR to enable colored output for recipe lines? You were the one who originally opened the issue, and I figure you might be a little more experienced with Rust than I am.

[frederikhors]

I'm sorry. I'm not using it anymore.

[avi-cenna]

@frederikhors , no problem at all, and thank you for your reply. If I may ask, what do you use now instead of just?

I was going to create an issue for this but there already is an MR, thanks @avi-cenna !

A question: why the limitation to cyan and purple instead of all the "base" colours usually found in terminal emulators ?

[avi-cenna]

@poliorcetics I wanted to start off with just a couple colors until someone could review and confirm that my approach was reasonable. Thank you for the review. Are you a maintainer on this project?

Looks good, added a bunch of comments. We should also add all the rest of the colors that ansi_term supports.

[avi-cenna]

@casey thanks for the review. I have applied your suggestions as much as possible, and added the additional colors. I've also added one integration test for the command-color argument.

Nice, looks great! I made a couple changes: I sorted the command color values alphabetically and reworded the help text message. Merging now!
