Org Column in Thunderbird

[Max Nikulin]

Hi,

I am playing with a thunderbird add-on that may add an icon to folder 
view if Org Mode files contains a link to this message. It is not 
polished yet, but I suppose, you may try it

Installation requires more steps since it is necessary to setup so 
called native messaging host application that does real job scanning Org 
files for Mention-IDs.
