Title: Fixed deprecation warnings for use of Chef::Mixin::Language

During a chef-client run using chef-client::delete_validation results in the following warning under chef 11.x:

```
[2013-02-14T20:27:58+00:00] WARN: Chef::Mixin::Language is deprecated. Use either (or both)
Chef::DSL::PlatformIntrospection or Chef::DSL::DataQuery instead.

[2013-02-14T20:27:58+00:00] WARN: Called from:

/tmp/vagrant-chef-1/chef-solo-1/cookbooks/chef-client/libraries/helpers.rb:21:in `'
```

Changed Chef::Mixin::Language to Chef::DSL::PlatformIntrospection when running Chef >= 11.0.0.

In addition, fixed some minor formatting issues where real tabs were used instead of spaces.
