 A link object's link_category property is an array of the link category
 ids to which the link belongs.  In rare circumstances, though, it can be
 set to a scalar.

 Attached casts the link_category value to an array before calling
 array_map().  This avoids a PHP warning.

 Patch also optimizes the conditional logic a bit by turning the series of
 $field if statements into a single switch statement and by moving the
 esc_attr/esc_js logic into the only $context branch to which it applies.
