Code review comment for lp://qastaging/~indicator-applet-developers/indicator-messages/consolidate

Okay, so the updates on the branch of things that were done 8/20 by Pete
and myself.

* The action names can now have ':'s in the name.
* "Clear" and "Clear All" were made translatable.
* The accessibility strings were also made translatable and adjust based
on the state of the icon.
* Setting of the alert icon was modified to handle source updates as
well as added and removed sources.
* Desktop file actions are now gotten from the libindicator parser, but
no libindicator (thus GTK) dep was added.
* The Clear menu item is no sensitive based on whether there are items
to clear
* The base action has been updated from (sssb) to the more modern a{sv}

I think that's all the issues that were listed in the comments.
