Generator AUTHORS.md contains escape characters around brackets

[Ian Kenney]

The generated AUTHORS.md file contains escape characters for brackets around the handle/email field (see below from mdakithole2 initial commit). The template file doesn't have the backslashes, so I'm not sure why it added them.

I think just to look nice on GitHub, but it should probably go.
