make some bug 1090 warnings go away

Browse Source 
When we excluded some Exits, we were sometimes warning the user that we
were going to use the node regardless. Many of those warnings were in
fact bogus, because the relay in question was not used to connect to
the outside world.

Based on patch by Rotor, thanks!

controller when we want to inform the user of overall success or
overall failure. Bugfix on 0.1.2.6-alpha. Fixes bug 1075. Reported
by SwissTorExit.
- Don't warn when we're using a circuit that ends with a node
excluded in ExcludeExitNodes, but the circuit is not used to access
the outside world. This should help fix bug 1090. Bugfix on
0.2.1.6-alpha.
o Minor features:
- Add a "getinfo status/accepted-server-descriptor" controller
