Human-readable license names

[ratijas]

APACHE_2_0 is for machines, "Apache 2.0" is for human beings.

I suggest adding a mapping for well-known license names for use in UI.

Check out GitHub's licenses API for names, identifiers and more: https://developer.github.com/v3/licenses/

Hi, thanks for the feedback! I agree that the licenses should be human readable. I'll see if I get the time to fix this.
