Configurable for the end-user

The project received its second configuration file. It's called config.properties, is in the root of the project directory, and currently contains 4 performance related settings. Feel free to use it, you have to check out the source from the SVN repository for that. Most important setting is RENDER_DISTANCE, you can set it to a lower value if jcrpg eats your GPU/CPU with higher values.

Also the memory eater has been located end removed, and some cache aging algorithm has been implemented in SharedNodeCache and (model file) BinaryCache for memory use optimization.

P.S.: The new great pine and distance based fog fadeout is in the is in SVN repository too.
