Make updates happen less if the server is under high load

[mike]

Feature

When the server is under high load, updates should happen less often. This should go for both the clients and remote servers.

Solution

Added some functions in Server class to figure out the average iterations per second over the last 40 iterations or so. Also made some functions to get the ips/desired ips for a load percentage (0%= full load).

Added code to odeArea to only update a certain number of objects depending on the load of the server. Similarly, caused odeRealm to only check collision/iterate a number of times that is dependant on the load.

Finally, added load as one of the parameters to determining if sending an update to a client was a good idea or not. (PlayerView?)
