Support relative paths about sourcekitten

[jpsim]

You have to pass in an absolute path for now

[jpsim]

@Keithbsmiley did you ever try again by passing in the absolute path?

[keith]

Yea that worked fine. Didn't know if you wanted this open as a reference or not.

[jpsim]

now that I've changed the title, it's more of a feature request, so we'll keep that open 😄.

Speaking of which, do you know what the Foundation equivalent of Ruby's File.expand_path would be? Looks like it might be stringByStandardizingPath.

[segiddins]

NSString.pathWithComponents(NSFileManager.defaultManager().currentDirectoryPath, userPath).stringByStandardizingPath

?

[keith]

Might have to check if the path that was given is absolute first.

[segiddins]

let absolutePath: String = {
    if (userPath as NSString).absolutePath {
        return userPath
    }
    else {
        return NSString.pathWithComponents([NSFileManager.defaultManager().currentDirectoryPath, userPath]).stringByStandardizingPath
    }
}()

Looks like a winner to me, wanna try that out, @segiddins?
