Make mouse clicklook report only the specific tile

Previously the mouse clicklook mentioned every tile that matched
the character symbol, leading to overload of information and
if playing with tiles, it was mostly useless. Also the most
important bit - the tile info - was last in the text.

Now mouse clicklook only reports the exact tile information
that was clicked on.
