[PATCH] make default raster image path relative to tileindex file

The attached path makes the path of image files for a TILEINDEX layer 
relative to the directory of the TILEINDEX shapefile, if the map's 
SHAPEPATH is not set.

I prefer having the path fall back to the TILEINDEX file's directory 
rather than the mapfile directory, because the tile index file and the 
raster imagery tend to be colocated, on a large volume separate from the 
mapfile.  Maybe there are some good reasons for relative-to-mapfile 
behavior too, but I couldn't think of any.  Behavior is unchanged if the 

The patch also removes an unused variable from msDrawRaster() and prints 
out the full (instead of relative) path of a raster file if that file 
could not be opened.  Printing the full path helped me with error 
resolution; some might consider it less secure to be displaying it though.
