LICENSE generation with meta-variables

[hrszpuk]

Is your feature request related to a problem? Please describe. LICENSE generation was an original aim for ReCTx version 2.0.0.

Describe the solution you'd like The solution is fairly simple, the user will be able to select any license available through rectx (or simple choose to not generate any license), then during project generation, a LICENSE file will be generated.

For this, I will create a new package for generating licenses similar to how these is a package for generating templates. I will also be moving some of the config license management to the licenses package. The config package should only handle managing the config directory, abilities such as downloading files/data should be left up to templates/licenses packages.
