A try to make the other lists being saved using nbt.
Suggestion and support by Caagr98. (to use nbt tags instead of my original
plan)
Merge remote-tracking branch 'upstream/master'
Made the list saving work.
Some minor features.
Made connections saved using nbt too.
Made message configurable.
Leave it empty and it doesn't print out anything.
Minor change.
More work on the session interface.
Added javadoc to the static methods in Session.
Implementation after this I guess.
Two item fixes.
More work + improved computer message.
Resume bug fix and increased security.
Removed debug code.
Added compability to old save format.
Merge pull request #34 from kirderf1/master

Various fixes.
