Removed openssl-nonblock, as it is no longer necessary

[Aaron1011]

It has been stated here by the gem's author that openssl-nonblock is no longer necessary with any supported version of Ruby.

[dbussink]

openssl-nonblock is also not necessary for 1.8.7, only for 1.8.6 and <= 1.9.2

[Aaron1011]

@logankoester: Can you please take a look at this? My PR at https://github.com/travis-ci/travis/pull/64 needs this to be merged, as openssl-nonblock fails to build on Rubinius.

[adamyeats-zz]

@logankoester, this was a small change so I merged this commit myself so our friends at TravisCI can continue with their project. Hope you don't mind. :)

[Aaron1011]

@adamyeats, the newest version of this gem needs to be released to RubyGems, so we can add it to the gemspec at Travis CI.

[adamyeats-zz]

@Aaron1011: Before I release to RubyGems, I need to look into why the build is still failing on rbx-19mode (and also jruby-18mode).

Here's the stack trace from the failing build if you can tell what's going on here:

[dbussink]

ruby-debug doesn't work on Rubinius because it accesses internals of the virtual machine. Rubinius has a built in debugger, so ruby-debug is not needed there.

[dbussink]

You probably want to use :mri_19 as the platform for ruby_debug and not :ruby_19.

[Aaron1011]

The problem is that when the PR got merged, my version of the Gemfile got left out. You want to put ruby-debug into group :debug.

[Aaron1011]

The .travis.yml is set up to exclude it from installation on Travis CI, as no one is doing any debugging when the tests are running.

[Aaron1011]

I've added in json as a dependency for Ruby 18 in PR https://github.com/pusher/pusher-ruby-client/pull/18.
