Merge lp:~townsend/libertine/refresh-libertine-scope into lp:libertine

[Christopher Townsend]

Invalid Libertine Scope results after successfully installing or removing a package.

I tried to use the Python dbus module, but trying to find a simple way to just send a signal is not trivial. I was spending too much time trying to figure that out when the solution proposed here works.

Should we also send a signal when we create/destroy containers?

Also see inline comments.

A few changes based on feedback.

> Should we also send a signal when we create/destroy containers?
For destroying, definitely yes since there are probably packages installed and they will get wiped.

For creating, well, there won't be any new packages on a freshly created container, but I guess it won't hurt.
