Lode Runner version 2.11a, AI_VERSION=4

(1) Modified for AI VERSION = 4
   (1.1) When guard failing in hole, will drop gold before guard failing into hole totally
   (1.2) Shake time extension when guard in hole.
         NOW the runner can dig three hold for three guards and pass through them. (MUST quickly)
	 ==> The behavior almost same as original lode runner (APPLE-II version).
