Fixed crash on DS in current version of SE

Removed the restriction on the number of supported factions.
You should now be able to register as many factions as you want.

Some minor optimization changes mostly provided by Remaarn again.

Includes fixes from Remaarn (MANY THANKS) to prevent crashes when firing at distant objects.

Made flush no longer clear the local settings
Since local settings are global for both local saves and servers you will often have factions that aren't in your current session.

Fixed Tracers not having their base velocity set.
