Fixed the API calls for watching and unwatching a repo

[aaronbloomfield]

As per https://developer.github.com/v3/activity/watching/, it seems the "watched" part of the URL to handle watching and unwatching a repo should be "subscriptions" instead. The updated URL (in this pull request) worked fine for me; the original one didn't.

Thank you :) .

But method names should be change as well but old methods proxies to new ones.

Also please fixed test and documentation into your PR and it will be perfect :) .

@Nek- the github UI still talks abotu watching, so it may be fine to keep watch() and unwatch()

[stof]

@aaronbloomfield please update the tests as well

@stof disagree with you. Github keep them only to keep BC. Our methods will fail as soon as they think it's time to remove theses entries. To be sure to provide data as expected, IMO we should set a proxy to the new method.

Why do you think that it's better to keep old entry point ?

I'm not talking about keeping the implementation based on the old endpoint, but about keeping the name watch and unwatch, as it is what the UI uses:

(sorry for the delay on this)

I've added a subscribe() and unsubscribe() method, while keeping the watch() and unwatch() method; the latter two have been marked in the comments as deprecated. This should allow existing code to continue to use watch() and unwatch().

The tests were all updated (and ones added for subscribe() and unsubscribe()), and TravisCI is happy!

👍 Thanks

Note for merger: the documentation should be updated.

[stof]

It would be better to write it as @deprecated use unsubscribe() instead, to match common deprecation messages
