 * direction to player is changed (ie zig or zag).  Continue zig zag until either
 * reach player or path is blocked.  Thus, will only return true if there is a free
 * path to player.  Though path may not be a straight line. Note that it will find
 * player hiding along a corridor at right angles to the corridor with the monster.
 *
 * Modified by MSW 2001-08-06 to handle tiled maps. Various notes:
 * 1) With DETOUR_AMOUNT being 2, it should still go and find players hiding
 * down corriders.
 * 2) I think the old code was broken if the first direction the monster
 * should move was blocked - the code would store the first direction without
 * verifying that the player can actually move in that direction.  The new
 * code does not store anything in firstdir until we have verified that the
 * monster can in fact move one space in that direction.
 * 3) I'm not sure how good this code will be for moving multipart monsters,
 * since only simple checks to blocked are being called, which could mean the monster
 * is blocking itself.

Log Message:	implemented proper support for empty treasures, which sadly occur in empty treasure lists. fixing treasurelists to have no entries at all would be even more complicated, but even when this is fixed, the current changes only make the server more crash robust to bad treasures. Also removed the 'NONE' specialcase for treasure lists. Developers should use 'none' instead now.
