16.04 casper 15_autologin file contains obsolete lightdm configuration

[fossfreedom]

/usr/share/initramfs-tools/scripts/casper-bottom/15autologin

the lightdm section of the file contains a lightdm configuration that is incorrect for 15.10 and later

for example it writes out /root/etc/lightdm/lightdm.conf

according to the lightdm wiki this should be /root/etc/lightdm/lightdm.conf.d/xyz.conf

Additionally using [SeatDefaults] is wrong. Again according the wiki [SeatDefaults] is obsolete and should be [Seat:*]

Think this is probably why manual live CD creators and those who use Pinguy ISO Builder cannot create a lightdm autologin live CD

While this configuration is old, it will continue to work. However, if this file is changed then accountsservice should also be updated to look in the new location.

I did look at this a while ago and decided it was too much to fix (and I'm not confident enough in this area) when I changed the configuration file conventions. It should be updated however.

It should be fixed at some point though.

Taking off the incoming list. It's a low-priority bug that we should fix, but it seems like it isn't urgent for the AA release.
