homebrew/brew repository missing license / copyright notices for bundled gems

[williamfligor]

It looks like homebrew/brew includes copies of ruby source for many gems, including webrick. Webrick is licensed GPL and unless I misunderstand the requirements, when the lib source is copied to this repo this repo has to also copy and include the notice (LICENSE.txt) in some way. I do not see that in the brew repository for any of the gems.

Webrick should probably not be there at all. I'll sort that and look at the licenses for those that should be there.

The files will likely appear with a brew install-bundler-gems, so it's just missing from the repo.
