 * reach player or path is blocked.  Thus, will only return true if there is a free

 *
 * 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.
