init() method

Hi,

we recently got the following feature request:
http://pear.php.net/bugs/bug.php?id=6215

To cite from a comment I made there:

While thinking about this request I have begun wondering if we should
not severely trim down init() to essentially just the _unfreeze() call,
the idle/expire handling and the forceLogin event.

It would then be up to the user to call login() and logout()
themselves. This would obviously be a big BC break.

regards,
Lukas
