Creating update.properties

The updated files now need to be signed in a way that hides the signature from Java. This way we can use a long time key without risking evil-grade attacks.

The signatures are saved in update.properties and generated by

java -cp .:classes games.stendhal.tools.updateprop.UpdatePropUpdater /tmp/update-0.86.properties /tmp/out.txt 0.94 0.94.5 build/lib stendhal-0.94.5.jar stendhal-data-0.94.5.jar stendhal-data-diff-0.94-0.94.5.jar ...
