Force announce not working for some trackers

[GoogleCodeExporter]

Mininova tracker is one example where force announce results in no feedback 
from libtorrent and wireshark shows no tracker traffic until the next_announce 
30min has elapsed.

Tested with 0.15.6

I just revisited this code as part of fixing ticket #232. I believe that patch 
should fix this problem as well. Please give RC_0_15 head (or trunk) a try.

actually, this could also be caused by the _min_announce_ not having expired 
yet. libtorrent will not violate a trackers request of min_announce. There is 
no feedback that the min announce hasn't expired yet, when a reannounce is 
attempted. It is however easy to look at the min_announce field to see if it's 
still >0 (it's a count down).

Would you suggest an alert being posted when this happens? Or did you have some 
other kind of notification in mind?
