wunderground_parse_atts() function

* Fixed: Added checks to make sure `numdays` is always less than 10
* Added: `hidedata` attribute that works like `showdata`, but in
reverse. By default, all items are shown when embedding the shortcode
(conditions, precipitation %, icon, etc). If you want to hide the icon,
for example, you would add `hidedata="icon"` to the shortcode.
