Function get_name_for_icon splitted
The function get_name_for_icon returns now the name of the icon,
without the full icon path and without extension (.xpm). Now is
not static.
The full path, including the folder creation, is done now by
wmkdirhier() (WINGs). This function is much better, because
supports "infinite" folders, not like the old get_name_for_icon
which could only create the specific folder for Cache Icons.
Using this functions, wIconStore() do the same work, but in a better
way, more clear.
