Support the wingpanel indicator API

[quequotion]

I know it's asking a lot for you to go out of your way to create an indicator for a niche DE like Pantheon, but there's currently no alternative for putting a sensor readout in the notification area.

elementary OS has dropped support of Ayatana indicators following GNOME's lead in enforcing Human Interface Guidelines that call for an end to application indicators--the notification area will only be used for system indicators in a future version of GNOME Shell as well (which is to be Ubuntu's default desktop following the death of Unity).

I think a sensor readout qualifies.

There is a sample indicator written in Vala (the primary language used in elementary OS development):

However, I think the indicator could just as well be written in C.
