[arm/release] Delaying connection resolution until after init

[arm/release] fix: Stacktrace from unjoined thread at shutdown

[arm/release] Hack to allow the descriptor popup to function for the new connection panel. This will probably be dropped when raw control port access is introduced.

commit 97789357dea31bfee8843da1410b9820623fbdbc Author: Damian Johnson <atagar(a)torproject.org> Date: Tue Apr 12 16:40:25 2011 +0000 Hack to allow the descriptor popup to function for the new connection panel. This will probably be dropped when raw control port access is introduced. This was the last piece of important partiy between the panels so the old connection panel can now be dropped from the codebase.
