[orca-list] Heads up: yaml is out, json is in, the settings dialog will pop up again

[Joanmarie Diggs <joanied gnome org>]

Hey all.

Funny thing about being under the umbrella of a bigger group like GNOME: 
There are rules. <grin> Yaml is not an officially-blessed external 
dependency of GNOME. So yaml had to go. Javi has done the work to give 
us a new json backend (thanks Javi!!). And, yes, we know this one is 
blessed as members of the GNOME Release Team were the ones who suggested 
a json conversion. ;-)

Due to the format change, I'm afraid those of you who regularly pull 
from master will find themselves in the settings dialog yet again. 
Apologies for any inconvenience.

Take care.
