Use SPDX IDs

[jacobmischka]

It would be nice if we could somehow map the common license abbreviations to the correct template.

For example, being able to specify -l Apache-2.0 and have it correctly use the apache2 template.

#6 would benefit heavily from this, as license values in package.json will rarely directly map to one of the templates.

Note that SPDX solves this issue in a standard way - see issue #14 and the fork that's referenced from it (soon to become a PR cc @maoo).

Switching to SPDX License Identifiers not only does away with any ambiguity, it also adopts a well-established standard for license identifiers (i.e. those used within the Linux Foundation).

SPDX is exactly what I was referring to, I just didn't know the name, thanks!
