* doc/contributors.rdoc: [DOC] Import contributors from redmine wiki
  Many wiki pages have become outdated and spam-ridden, we will import
  these to trunk and begin maintaining them in ruby-trunk. This will
  also allow new contributors to easily contribute patches to update
  these pages, where previously a redmine account with wiki access was
  required. Another bonus is having a contributors file to show thanks
  to all of the people who have submitted a patch to Ruby.
