Examples in conditional_statements quest out of date

[dwysocki]

The conditional_statements quest makes several references to the Apache module, referencing specific lines of code. These lines have been changed since the quest was last updated, and the changes are a bit confusing as they make use of slightly different Puppet language features than what's highlighted.

I recommend changing the links to the Apache module on GitHub to permalinks which match the references in the quest document, rather than a link to the latest version.
