[Authentication] Launching the secret service

[Michael Leupold]

Hi there,

I figured we haven't actually talked about how a user's desktop decides which 
implementation of the secret service to launch and how it is actually 
launched.

As to which daemon is launched we could integrate with xdg-utils by creating 
an xdg-secret-service script which launches the daemon configured by the user.

Regarding the how D-Bus activation seems to be the way to go. It seems gnome-
keyring already uses that approach. Does it work alright like that?

Regards,
Michael
