Subject: [PATCH] rnd-20080930-1-src * fixed bug with player relocation while
 the player switches an element * fixed bug with EM/DC style exit and EM/DC
 style steel exit which was   not walkable (and did not let the player enter)
 when in process of   opening, but not fully open yet (which can cause the
 player not being   able to enter the exit in EM/DC style levels in time)
