[Gzz] Save progress

[Matti Katila]

Hi Tuomas!

Any ideas what's missing because save now works partially. The problem 
is with connection because them got lost when loading. Also I would like 
to know how can I set/move to the accursed cell from home cell so I 
wouldn't need to use n1 which is replaced when i reload the scene.


If you wanna test, try something like this:
mkdir /tmp/pp
start pp
make some new papers
ctrl+x save
make some more new papers and then
ctrl+z for load
it returns to save state but all connections are lost :P
