save reference to the event router rather than grabbing it twice?

change_str doesn't appear to be used?

[Greg Spencer (Chromium), 2013/02/12 23:11:02]

Removed.  That was for some debugging output that's no longer there.

why does OnNetworkListChanged take OnNetworksChange args and vice versa?
Seems... like it should be the other way around.

[Greg Spencer (Chromium), 2013/02/12 23:11:02]

Whoa.  I guess this worked because in the end they have the same argument types.
Thanks for catching that.
