Added useExactLoginLocation(). Closes BUKKIT-145

useExactLoginLocation() looks for settings.use-exact-login-location within bukkit.yml.

If true, we will bypass Vanilla's behaviour of checking for collisions and moving the player if needed when they login.

If false, we will continue to follow Vanilla's behaviour and move players that 'collide' with objects when they login.
