Unify method for copying special files from repo to site

[benbalter]

In support of #4596, this pull request introduces a siteify method to the rake tasks, to DRY up copying markdown files from the root to the site (CONDUCT, CONTRIBUTING, and HISTORY).

Can we add a bit of splitting to that method please? Perhaps use Pathname or Pathutil? Anything that merges the logic of all that File# stuff, including the replacement of extensions.

@envygeeks I'm afraid I don't follow. Can you elaborate?

[envygeeks]

@benbalter Pathutil can encapsulate everything you did more more cleanly.

file = Pathutil.new(file)
data = file.read
contents = "stuff"

file.sub_ext(".md").write(
  contents
)

As stated before you'll have to manually add pathutils gem to the Jekyll dependencies until my pull to convert all our stuff to Pathutil gets in there but for now we can at least start doing bits and pieces more organized like.

@envygeeks started to implement things, and think a refactor like that is better suited for a subsequent pull request to keep this one targeted. The abstraction isn't as clean because we're actually working with two different files.

I would prefer to leave this out. I believe our changelog generator will nix it anyway.

[benbalter]

I think it's called History.markdown

Good call. Fixed.

Thanks, Ben!
