Rugby Lua v1.2 by Darren Watts

This is a lua script that is meant to go with the Rugby gametype for alephone.  Teams are red vs blue.  The objective of rugby is to take the ball into the opponent's base.

This script mostly just helps let you know what is going on during the game.  If you do not have the ball, the compass will point to it.  If you have the ball it will point to the enemy's base.

The script also resets the ball if it lands on an "item impassable" polygon or if no one has touched the ball in 20 seconds.  If you bring the ball to your own team's goal, the opposing team will get a point.

Changes in v1.2:
1) Fix a bug where the script will incorrectly determine that you scored a point on your own goal.

Changes in v1.1:
1) More efficient code.  There should no longer be a drop in fps using this script.
2) Remove base life regeneration code, it wasn't being used and wasn't really helpful anyway.
3) The opposing team now gets a point if you take the ball into your own goal.
4) Countdown to the time the ball first spawns.
5) Reset the ball immediately if it falls on an "item impassable" polygon.
