Ruth/Zion with more memory now

Ruth/Zion is now running with 1Gb of memory - thanks ldvoipeng!

Also, I've added the [Chat] section to the .ini file - appears without it, the opensim crashes on startup.

Now everything is up and running back again. The physics seems to behave a bit odd though... but I'll play with it later on. The RL still will be dense, so feel free to login and mess around while I am not there :-)
