Bug 26544: Add housebound details to delivery page

To test:
1. Turn on the housebound module
2. go to the housebound for a given patron /cgi-bin/koha/members/housebound.pl?borrowernumber=X
3. add some housebound details, fill out all the fields
4. Go to 'Add a new delivery'
5. No housebound details, hard to know what the patron likes or days to deliver!
6. apply patch
7. Go to 'Add a delivery'
8. See the housebound details, yay! All the line breaks should be preserved.
