Bug 28810: replace housebould detail inputs with textarea

Bug 28810: replace housebould detail inputs with textarea

To test:
1. apply patch
2. enable housebound module
3. go to a patron and look at the housebound tab
4. Edit the detials.
5. The preferred materials, subjects, authors, referral, and note inputs should be replace with much larger textareas.
6. You should now be able to added line breaks, so fill out each of the fields adding some line breaks. I added something like:
Fiction authors: Frank Herbert
Non-fiction authors: Malcolm Gladwell

7. Save changes
8. Now when you look at the housebound details those line breaks should be preserved and much easier to read.
