Ugg this feature is a pita. Giving the user a notice that it'll break the
system utilities that arm relies on, telling them how to disable it and where
to go for more information.

Unrecognized event types are neither important nor something that a user can be
expected to fix. Actually, it's an issue for the controller library (torctl or
stem). Dropping these below the default runlevel.

Arm is currently complaining about SIGNAL and CONF_CHANGED not being
recognized. If torctl doesn't add support for these then this won't be
addressed until our move to stem.

The connecion panel provides information from two sources: connections from
system utilities and circuits from tor. We had a check that prevented the
connection panel from being updated when the former didn't have any new
information, which in turn broke the panel entirely when connection resolvers
either failed or were disabled.

The 'is new connecion results available' check was actually pretty pointless.
The update method gets called every five seconds and the connection resolvers
operate at a similar rate (maybe every ten seconds? it depends on resolver
performance) so it didn't actually buy us much.

Removed the check.

Now that we have SafeCookie this is gonna be a common warning until we add
handling for it. This isn't a notice that should be user facing - it indicates
something useful to me, but not users.

The 'GETINFO circuit-status' output has an *optional* third arguement that is a
path. This is a pita because it's essentially an optional positional arguement
that can have '=', so we need to differentiate it from the key=value entities
that follow.

This resulted in confusing 'Unable to determine fingerprint' warnings, and
seemed to cause a screwed up circuit listing. Ticket tracking this is...

Adding the same sort of icon svg that I used on the website. This is based on
'utilities-system-monitor.svg' from the Oxygen icon set, which is used by KDE
and under GPLv2 and CC v3 (A, SA).

Also adding a '.desktop' metadata file for the arm gui provided by Juan.

Part of the code that I copied from TorCtl raises an IOError when we get an
unrecognized auth method (my bad, I wrote it). Changing that in our copy to
log a warning instead. Caught by "E" (email subject: SAFECOOKIE)

Tweak for the preceeding comment and including the ticket with the comment.
