Log Message:
Update ruby-rspec-support to 3.4.1.

### 3.4.1 / 2015-11-20
[Full Changelog](http://github.com/rspec/rspec-support/compare/v3.4.0...v3.4.1)

Bug Fixes:

* Fix `RSpec::Support::RubyFeature.ripper_supported?` so it returns
  `false` on Rubinius since the Rubinius team has no plans to support
  it. This prevents rspec-core from trying to load and use ripper to
  extract failure snippets. (Aaron Stone, #251)

### 3.4.0 / 2015-11-11
[Full Changelog](http://github.com/rspec/rspec-support/compare/v3.3.0...v3.4.0)

Enhancements:

* Improve formatting of `Delegator` based objects (e.g. `SimpleDelgator`) in
  failure messages and diffs. (Andrew Horner, #215)
* Add `ComparableVersion`. (Yuji Nakayama, #245)
* Add `Ripper` support detection. (Yuji Nakayama, #245)

Bug Fixes:

* Work around bug in JRuby that reports that `attr_writer` methods
  have no parameters, causing RSpec's verifying doubles to wrongly
  fail when mocking or stubbing a writer method on JRuby. (Myron Marston, #225)
