Track GeoServer related items

[henrinormak]

There are several items that we are not currently properly sharing between each other, such as GeoServer styles, layers and other configuration, I will look into what files need to be placed where and based on that what files can we pull into the repository (if need be as duplicates that we need to move individually).

Done, look at README for instructions on how to use the shared data directory.
