Bug 7047: Storing subscription renewal note in suggestion to be displayed on the suggestion page.

Additionally I have added a library input field in case the librarian wants to set a library branch whilst renewing a subscription. With the use case being they may have ommitted to set the branchcode whilst creating the subscription.

Test plan:
1. Create a subscription (if one does not already exist)

2. Set the RenewSerialAddsSuggestion syspref to 'Add'

3. Renew the item making sure to write in a value into the note field

3. Visit the suggestions page and notice that the note is not displayed
for the newly created suggestion

4. Apply patch

5. Repeat step 3. Notice that there is now a new branchcode dropdown
box. Select one of your libraries and write in the value into the note
field

6. Visit suggestions and notice there is now a 'Suggestion note' column
in the table containing the note.

Also note that the suggestion has the correct branchcode associated with
it
