Licence missing in the rubygems version and in the gemspec

[mensfeld]

Hey, as stated by Coditsu:

The "base58" gem seems not to have a license at all. Unless a license that specifies otherwise is included, nobody else can use, copy, distribute, or modify that library without being at risk of take-downs, shake-downs, or litigation.

https://rubygems.org/gems/base58 => Licence: N/A

Fixed in 0.2.3.

Thanks for making me aware of this.

Wow that was fast! No problem, we monitor things like that to avoid legal problems. Thank you for such a fast response and your work on this library!
