Warn when activating a gem with known avisories

[nogweii]

With this plugin installed, Rubygems should issue a warning whenever it activates a gem with known advisories.

Last I heard, RubyGems only enables plugins when running the gem command.

I was thinking more along the lines of hooking into RubyGems's overriden Kernel#require. Reading the source, the best place would be to include the logic into Gem::Specification#activate, but I don't know if there is a hook of sorts for that.

Ah that's an interesting idea. I might make a separate library that checks your installed gems and provides such a monkey-patch.
