Added license information to package info.

[anyt]

As license information optional, but is highly recommended to supply, it's important to have it in package information if it possible.

Thank you for your efforts!
But I really doubt license information to be of any profit while it takes it's space (very little but still).
I prefer to keep packages files as little as possible cause they are downloaded to users' computers.
Thus we add to packages files only those information that is really necessary to make it functional.

So if there are any reasons tell me, else sorry - no license :)

There are tools that checks license of all dependencies for possible violations (for example using GPL library in proprietary app). There is also composer licenses command.

Don't think that these few bytes more will make any difference.

Good reason.

Thanks everybody!
Will get to prod eventually.
