Rename AbsolutePath's `join` method to `appending` to better match the
semantics ("join" is usually applied to a collection to combine all of
its elements, while "append" is usually applied to one thing, such as a
string or collection, to tack another thing onto the end of it).
The `-ing` suffix also makes the name more inline with Swift 3 naming.
