Added 'skinny show lines verbose'

This will print the subs and their status for every line (if any).

wedhorn did most of the work with his patch which introduced
'skinny show debug' but a discussion on IRC stated that it should be
added to 'skinny show lines'

Input on the output format by Qwell on IRC.

(closes issue #13344)
