Log Message:
Some package i'm working on needs this >=1.0.0. Since nothing depends on it,
i don't see this update breaking anything. rubygems says that package requires
ruby>=1.9.2, so removing 1.8 from supported versions. This package needs to be
renamed to ruby-rubyzip, because there is a ruby-zip which is not this package.
