Name input screen should be deactivable

[quidam]

The "enter your name" screen is only needed in live environments. If Sugar is ran in a normal installed to disk environment, the user will need to provide a name and password to start the session, so asking for a name again is not needed (as it could be loaded from $USER).

A configuration file enabling or disabling the screen would be the best way to do this, as it would allow the session loader to avoid distribution-dependent checks.

predefined values:
* "disabled" ask nick on initialization
* "passwd" use gecos/name from passwd file
* otherwise use prop value as is for nick value

This is just about the default text for the name prompt, right? The name prompt will still get shown?

In attached patch, the name prompt will be shown only if default_nick is disabled.

Sounds good to me, some comments:

- s/passwd/system?

- can we use a more descriptive name than 'pw'?

Thanks, please push.
