Fix debian package dependencies.
Use /etc/puavo/device.json tags to pick up autopilot configuration.
Use "write_line('humppaa')" instead of "humppaa()".
In /usr/bin/puavo-autopilot-session do read /etc/puavo/device.json
to figure out if anything should be done.  Pick up the mode
from there if it has been set up (only "stress" is supported
thus far), and then do the work.
Rename I99-lightdm-login to I99-lightdm-puavo-autopilot-login
and fix its syntax.
Make puavo-autopilot-session mode handling more sensible.
Now the mode gets chosen based on current user and tags.
This is also needed for ltsp servers so that we can put
ltsp servers into test, while normal users can also login
and do their work.
Fix puavo-autopilot-session.
Document puavo-autopilot stuff.
