/**\brief Update the Projectile
 *
 * Projectiles do all the normal Sprite things like moving.
 * Projectiles check for collisions with nearby Ships, and if they collide,
 * they deal damage to that ship. Note that since each projectile knows which ship fired it and will never collide with them.
 *
 * Projectiles have a life time limit (in milli-seconds).  Each tick they need
 * to check if they've lived to long and need to disappear.
 *
 * Projectiles have the ability to track down a specific target.  This only
 * means that they will turn slightly to head towards their target.
