Swap key and value in $supported_icons array

Before, since the icon class was the key, only one URL pattern could
be associated with each icon. By swapping these, multiple patterns can
now be used for a single icon. So a user could filter this array and
add their own URL pattern and then define any FontAwesome icon to use
with it.
Ensure that section IDs are strings.
Avoid notice when array is not an array.
