Opie login becomes useable now:
- pre- and post-session scripts (in $OPIEDIR/share/opie-login) to fix things like device ownership to user/root - logging in now doesn't simply mean: execute bin/qpe. instead opie-login * first tries to execute ~/.opie-session * if that doesn't exist $OPIEDIR/share/opie-login/opie-session * if that fails too, execute $OPIEDIR/bin/qpe you can now handle things like ssh-agent on a per-user basis. (I'll commit the scripts later - for now it simply works like before)
