Remove “Mono” from the prefix of names of custom families

[matj1]

The names of the custom families always start with “Rec Mono”, even if the fonts are proportional (with MONO < 1), and that can lead to wrong names.

I would like that the “Mono” would be removed. The automatic name prefix “Rec Mono” could be replaced by something else; I came up with these variants:

• “Recursive”
• “Rec”
• “Rec Code”

I like “Rec Code” the most for its similarity to “Rec Mono” but being more general. Also, it reflects better the intent of this configurator to customize Recursive for code.

You’re right, that is better. This is a change I had sort of been pondering, but never got around to. But... it was helpful to see that you had similar thinking, and the change was super easy to make, so, done! It’s added to the proportional branch and PR #25
