- fixed some issues with the PathTraverse and sight checking code:

Browse source 
* typo in calculating end position from a trace vector
 * must use floor to convert from floating point block coordinate to block index to account for running off the negative side of the blockmap. (Int cast always rounds toward zero which is wrong here.)
 * bad calculation of sight checking slopes - they has the actor's z coordinate duplicated.

- fixed scaling of automap markers.
