Fix README example spec to display actual output
Ensure let block is not passed to super call.

Fix #820. This is directly related to bug
http://bugs.ruby-lang.org/issues/8059.  It seems to affect Ruby 1.9.3
but not Ruby 2.0.0. As per the notes, it is a heisenbug, so simply
looking at it causes the bug to disappear.

Force the call to super to make sure the let block is not passed in.
Update Changelog with issue description.
Relax the ZenTest dependency.

4.6.2 will no longer install on travis because it requires rubygems ~> 1.8, and travis now has rubygems 2.0 installed.

Fix README example spec to display actual output
Fix travis CI build.

- Bundler 1.3 needs rbconfig to be required to run `bin/rspec` after
  installing with `--standalone --binstubs`.
  https://github.com/carlhuda/bundler/issues/2382
- The Travis VMs no longer have 32-bit JVMs available. Aruba 0.4.11
  forced the -d32 flag. 0.5 just documents it and makes a file available
  to require that will set it. We've updated Aruba here so that the jruby
  ENV vars aren't set automatically; we've kept the flag to disable JIT
  but removed -d32.
- Aruba now has a "the file xyz shoudl contain" step.
bin/cucumber needs rbconfig required, too.
rbconfig must be loaded before bundler/setup
I'm still getting undefined const RbConfig on travis.

I think this should fix it.
No need for this before_install script.
Allow a longer timeout on JRuby.
