Updating The Default Gemset For A Ruby In RVM

I've been messing around with my .irbrc file lately, and I've decided to use some new gems. So then I needed to go back through all my rubies to update their global gemset.

I found this post that describes how to uninstall a gem from the global gemset

rvm use 2.0.0
rvm @global do gem install wirble awesome_print looksee hirb --no-rdoc --no-ri

Note that looksee isn't Ruby 2.0 ready yet, so it'll fail.
