Infinite Sessions

Hi Dave,

My infinite session expired. So I did a little debugging and I think I have solved your problem (assuming that there is a problem and I didn't make some other mistake).
Firstly though - in the app setup your give a link to get session key and mention that if prompted tick the box to prevent session from expiring.... I can't seem to do this. Is it an old feature that doesn't exist in new facebook? If I am already logged into FB it goes straight to session details. If I log out it just won't work (says the url doesn't exist).

I notice in fb_infinite that you have a field for the one time code but you say you couldn't get it to work.
I turned on the api debug ($conf['fb_debug']= TRUE; in settings.php) and noticed that it didn't seem to be sending the session details.
Then I realized that it was because I was administering from a non fb user (my admin user). I'm not sure if administering from fb user is an option, but I don't think so, because I gave it a try and editing the app seem to have some issues.

So that lead me to making some changes to fb_infinite_nodeapi
1. Make it a two step process. First save the session key to the app. Then go back and save the one time code. Thus you can use FB_FBU_INFINITE_SESSION rather then the non existent "current" session.
2. $fb_app doesn't seem to exist and $node->fb_app doesn't seem to have all the data. So get a new $fb_app using $node->nid.

In short I changed this:
$fb = fb_api_init($fb_app, FB_FBU_CURRENT); // Does not set user.

to this:
$fb_app = fb_get_app(array('nid' => $node->nid));
$fb = fb_api_init($fb_app, FB_FBU_INFINITE_SESSION); // Does not set user.

The result was that the session key did not change, but the expiry was 0. So I am hoping this key won't expire now.
