License header not correctly templated

[Oliver Bertuch]

Describe the bug

When using setup.bash, choosing an MIT license does not replace [year] and [full name] in the license text.

Steps to reproduce

1. Create a new repo from this template.
2. Use setup.bash and choose MIT as your license.
3. Take a look at the generated LICENSE file.

Expected behavior

-Copyright (c) [year] [fullname]
+Copyright (c) 2020 Oliver Bertuch

I do not think this is a viable soln as some licenses require more user input than this, eg: agpl-3.0 has this placeholder also:

<one line to give the program's name and a brief idea of what it does.>

I will PR a soln that adds a TODO item into the license instead.

If anyone wishes to PR an automated solution, please do.
