Add deviceID to Playable for history entries

[glensc]

This is needed to identify devices from play history:

    history = movie.history()
    for h in history:
        print("- Watched: %s (%s) -> %s,%s" % (h.viewedAt, h.lastViewedAt, h.accountID, h.deviceID))

[glensc]

Also need some help, how to find Device based on that Id?

There's plex.systemDevices(), but it returns all devices, not the specific one I'm interested of.

Also, the offset is off by one when accessing as index, so need to use lookup;

I've come up with this:

    devices = plex.systemDevices()
    history = movie.history()
    for h in history:
        # device = devices[h.deviceID] <- devices is not indexed by deviceId
        device = next(x for x in devices if x.id == h.deviceID)

Using next() will work.

I added convenience methods to retrieve the account or device by ID in #703. The methods just use next() the same way.

Maybe (also) make the devices indeed by deviceId?

I don't know what you mean.

Oh, you mean the list index. No, the order comes from Plex. They start their IDs from 1. It would also fail if a device is ever deleted (I don't know how) causing IDs be skipped.
