Establish read-only bindings to GSettings from the indicator

The bindings to GSettings are established in the GTypeInstance _init
function of the indicator.  During this time, the property notify queue
is frozen.  After the construction completes, the queue thaws and the
rush of property change notifications causes GSettings writes to occur.

We can fix this by switching to using readonly bindings.
