Support GET /apps/[app_id]/channels/[channel_name]/users

[neilcauldwell]

Add support for the new GET users resource. Perhaps it could be accessed via Pusher.channel_info(name, :info => :users).

We've moved away from a method per REST API method (eg channel_info), and instead provide a generic interface, eg:

Pusher.get('/channels/[channel_name]/users', params)

[neilcauldwell]

Gotcha, thanks. Will Pusher::Client#channel_info be removed in a later version of the gem?

[maxthelion]

Not in the immediate short term.
