Bug 30955: Sends notice to new owner at transfer

This patch adds a new notice, TRANSFER_OWNERSHIP, under a new module,
Lists. When a list is transferred to a new owner, this notice is
triggered, containing a short paragraph detailing the list name.

TO TEST:
a)  log in as a koha superlibrarian
b)  go to the lists module, create a public list, and make a note of the
    title used
c)  on the lists module, transfer the list to some other user, and make
    a note of the user used
d)  go to the patron notices page for the user in step c
e)  ensure that a notice has been generated
    1)  check the contents of the notice, it should contain
      - the new owner's name
      - the list's title
      - the old owner's name & (if set) email
f)  under tools > notices, modify the notice for TRANSFER_OWNERSHIP
g)  repeat steps c-e
    1)  ensure the modifications you've made are now visible in the notice
