 Currently when you use ```wp_get_object_terms``` to request an array of
 IDs or tt_IDs, the array returned contains strings representing the IDs,
 not integers. This then creates issues if you send the values back into
 ```wp_set_object_terms``` as it creates terms named as per those strings,
 rather than associating the term_ids as expected.

 Code to prove the issue:

 {{{
 $term_ids = wp_get_object_terms( get_the_ID(), 'category', array( 'fields'
 => 'tt_ids' ) );
 var_dump( $term_ids );
 }}}

 Results in:

 {{{
 array
   0 => string '1' (length=1)
   1 => string '5' (length=1)
 }}}

 I believe that the array should have all values cast to integers before
 they are returned. The attached patch does this by mapping a created
 function to utilise ```(int)``` for the desired result.
