Combat milestone reached!

The combat code has now been completed and tested enough that it is at last possible to fire photon
torpedoes against a planet and eventually wipe out the population and take it over!
While you should eventually also be able to launch an assault on the planet to take it over without first trashing it and wiping out the population, this does mean that at last Imperium is truely playable from start to finish.
I will be looking at the assault code to see how much more work it needs, but barring any unexpected critical bugs the next release of the server should occur shortly...
