[tor-qa] Experimental 3.5.2 bundles with tor-fw-helper (automatic port forwarding)

[David Fifield]

Please test these experimental bundles that have tor-fw-helper included.
You may know that flash proxy requires people to set up port forwarding
(https://trac.torproject.org/projects/tor/wiki/FlashProxyHowto).
tor-fw-helper is a tool that uses UPnP or NAT-PMP to forward a port
automatically. I'm interested in finding out how likely it is to work.

https://people.torproject.org/~dcf/pt-bundle/3.5.2-fwhelper-1/

The bundles are configured to run flash proxy and tor-fw-helper. You
just have to click "Connect" and wait up to 60 seconds. You don't have
to do any special tests; just see whether it bootstraps or not.

If you want to see more of what's going on, look at the file
flashproxy-client.log that will be created inside the bundle. When
tor-fw-helper fails, it looks like this:

This is the branch from which the bundles are built. The second link
shows what's different in the branch relative to the TBB 3.5.2 release.
