Bug 10987: remove duplicate 'see also' and 'see from' labels from authority search results

If an authority record has more than one 4xx$a (or 5xx$a) entries the
corresponding labels 'see also' and 'used for/see from' werwe repeated.
This patch removes duplicate instances of the labels, improving
readability.

To test:
- Have authority records with more than one entry on the 4xx (or 5xx)
  fields.
- Do a search, check "see also:" (or 'used for/see from') appear more
  than once.
- Apply the patch
- Reload and check it looks nicer :-D
- Repeat for: staff auth search, OPAC using ccsr, OPAC using prog
- Signoff

Bug 10987: (follow-up) fix display of authorities containing only one see from or see also lnik

This patch fixes an incorrect test on the number of see from and
see also links in the authority record, as otherwise if a record
had only one 4XX or 5XX, the linked headings weren't displayed at
all.  This patch also makes the test consistent across the staff
theme and the two OPAC themes.
