Add wiz-only tile idx debug tooltips on dungeon.

Hovering the mouse over any cell on the dungeon display will now display the
contents of tile_fg, tile_bk_fg, and crawl_view.vbuf[x]->tile_fg (and the
corresponding background tiles too).  It displays them as index, flag (as hex),
and then name (with multiple names for any mcache entries that comprise
multiple tiles).  This should help debug weird tiles display issues.
