- Fixed some properties in GameServerSettings not being saved due to being private.

- Fixed serversettings.xml overriding the settings entered in the "host server" menu in the client project.
- Added a default serversettings.xml file.

TODO: either add an error/warning of some sort if trying to use any of the ObjectProperty attributes on a non-public property or make ObjectProperty compatible with private properties. + Refactor Properties.cs, class/method naming in particular.
