Better Adherence to Bittorrent tracker Announce specification

[pyckle]

This pull request makes the following improvements:

• Peers received from the initial tracker connection are now used rather than discarded
• BT no longer makes two calls to the tracker on startup - one to announce the startup and the other to get peers.
• BT now respects tracker minimum announce intervals
• BT now does not send a completed event to the tracker if the torrent was already completed before it connected to the tracker
• BT does not send start events to all trackers in torrents with multiple trackers. Rather it waits for
• The first tracker announce is synchronously waited for - this decreases the time to connect to the first peers returned from the tracker.

Still todo:

• Peers received from the completed event are not added/used
• Download / upload stats are not sent on tracker query events

Whoops. My mistake, should have deleted that.
