remove .ruby-gemset and .ruby-version
no more rbx 19 mode
add services: redis to .travis.yml
trying the same thing resque did, add ruby-sl dependencies to gemfile for rbx
using rubysl and racc, still getting one load error :(
use rubinius-profiler and rubinius-coverage gems

also changed profiler require line
bundler cache
cache bundler only for private repos i guess...
allow rbx failures for now :(
Merge branch 'resque/master'
