Few notable updates for documentation

[davey-h]

You've done fantastic work with this. Wanted to give you a few heads up on changes that I presume come from changes in the SoundCloud API

Resolve

Your example:

scPlayer.resolve('https://soundcloud.com/djangodjango/first-light', function (err, track) {
     ...
});

here err and track have swapped places to

scPlayer.resolve('https://soundcloud.com/djangodjango/first-light', function (track, err) {
     ...
});

TimeUpdate

Your example:

scPlayer.on('timeupdate', function (audio) {
    console.log(audio.currentTime);
});

I thought I had this figured out but I don't. The event is working right, but I'm not seeing the currentTime property come in. As a workaround I'm currently grabbing the current time from scPlayer.audio.currentTime when the event fires.

I'll update this if I find more. Sorry if this is the wrong place to notify, new to this contributing game :smile:
