Fetch all players in league

[brianzhou13]

Would it be possible to pull the available players on the waiver wire for a league?

Thanks!

This is a good request, thanks! It should in theory be possible with the player resource request in the Yahoo API. It will be a bit of a time consuming request (most leagues have hundreds if not thousands of players to fetch) but it should be doable

@mattdodge I have created a pull request with a couple of comments. Can you check it?

Awesome, thanks @xaph! Took a quick glance and it looks great, will do a deeper review in the next few days
