client: Implement Events() about go-dockerclient

Taking a channel allows the caller to specify it is done by closing the channel. Thoughts @fsouza?

I am willing to take a swing at this.

@jhulten the reader should never close the channel.

I imagine that Events(since uint64) could create a goroutine and write the output to a channel that it returns. Something like:

ch := make(chan type, size)
go func() {
  for _, event := range events {
     ch <- event
  }
  close(ch)
}()
return ch

What do you think?

I put a stake in the ground with #71. I will look at changing it to return a channel tomorrow.

Thank you, I will have a look within the next hours :)

Should this be closed now?

[fsouza]

Sure. Thanks!
