* 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.
