Store settings on Jabber ID #809
Description
Suppose I use Psi on my home computer.
Later, I install Psi on a new machine at office or in my vaccation home.
The settings of Psi of theme, behaviour are retrieved from PEP node xmpp:org.psi-im:settings of Jabber ID.
Yet, thinking of this further; "What if you are connecting with Psi on a friend's machine?"; One might not want to have logs saved into that machine.
Hence, one might want to have another set of settings when he is a guest of that machine.
So a (custom) profile indicator would be needed: xmpp:org.psi-im:settings:desktop, xmpp:org.psi-im:settings:guest, xmpp:org.psi-im:settings:travel etc.
In case PEP is not available (i.e. creation of a node fails), Psi would display a message that it can not use Jabber ID to synchronize account settings, and it would offer to contact the system administrator or switch a provider.
In case of conflicting settings, similarly to "dot new" files of Salix and Slackware, Psi would prompt to synchronize settings or keep them local, similarly to the group chat option to auto-join "only from this computer".
