Editing existing online IMAP account

[Aqeel Akber <aqeel akber gmail com>]

Hello all,

Gnome version: 3.16
Distro: Current Arch Linux

As far as I can tell there is no way to edit existing gnome online 
account details for IMAP or GMAIL type accounts. 

Creating a new account would mean all the email headers would need to 
be downloaded again in evolution and settings recreated. This is not 
ideal for minor changes in email account details. 

Where is the gnome online account information stored, and how can does 
one edit it? 

Cheers,
Aqeel
