port support for i2psnark torrents

[killyourtv]

When I added the test torrent from ​http://torrent.vuze.com/i2p/torrents/Azureus5.3.0.0.jar.i2p.torrent to i2psnark (after fetching it with wget), I got the following in the status window:

Torrent added and started: "Azureus5.3.0.0.jar"
Warning - No I2P trackers in "Azureus5.3.0.0.jar", will announce to I2P open trackers and DHT only.

The torrent has an I2P tracker within:

$ btshowmetainfo Azureus5.3.0.0.jar.i2p.torrent

Perhaps I2PSnark doesn't recognize trackers with ports as being within I2P?

Testing this, it works (the torrent can be downloaded) but the message about "no I2P trackers" is still shown:

Torrent added and started: "Azureus5301-B24.jar"

For testing, the torrents can be found at ​http://xdwlfjmvtw7awr6n5y3cxx64abid23pibyol3kd5hrjia64vpfba.b32.i2p

Sorry, there was a 2nd spot I missed before.
