Application does not save YouTube configuration

[Starz0r]

I was looking around recently for an application that would allow me to save time editing my Watch Later playlist on YouTube which is at maximum capacity. Luckily this application exists, so I didn't have to spend time writing it all myself.

There was an issue unfortunately, which I didn't initially understand why, but it wouldn't save configuration options. After some short investigating, it was because the application directory wasn't being created before it was used, so the config file wasn't being stored.

I've solved this issue in my pull request: #25

(This may be Windows-only specific behavior, but I can assure you the patch should work on all platforms 😃)
