Bug 14269: OPAC: Some template improvements for the full serial history page

- Fix filter labels:
  Library : -> Library:
  Subscription : -> Subscription:
- Make '(All)' entry in filter pull downs translatable
- Show branch name instead of branchcode in table and filter

To test:
- Verify changes as described above
- Verify filters still work as expected

Followed test plan. Works as expected.
