Bug 10948: make reference labels translatable in OPAC auth results

For some reason the translator script was not picking up the see also
and used for/see from labels on the OPAC. This patch fixes the problem.

To test:
1) Apply patch.
2) Generate PO files.
3) Note that "see from" and "used for/see from" appear.
4) Sign off.

Works nicely, thx for the fix.
Tested by updating the German po files, translating the
strings and installing the templates.
Verified strings show up in German in the authority
result list.

Bug 10806: make the staff benchmark script check authentication failure.

Currently, if you launch the script
misc/load_testing/benchmark_staff.pl, it always displays
"Authentication successful" or continue to execute the script even if
nothing is done.

This patch checks if the url is right and if the authentication is
correctly done.

Test plan:
Suppose that a correct login/pwd is koha/koha
1/
perl misc/load_testing/benchmark_staff.pl --steps=1
--url=http://admin.koha.local/cgi-bin/koha/
--password="koha" --user="koha"
should produce:
  Authentication successful
  ...
  Step 1
  ...

2/
perl misc/load_testing/benchmark_staff.pl --steps=1
--url=http://admin.koha.local/cgi-bin/koha/
--password="KOHA" --user="KOHA"
should produce:
Authentication failure: bad login/password

3/
perl misc/load_testing/benchmark_staff.pl --steps=1
--url=http://admin.kobe.local/cgi-bin/koha/
--password="koha" --user="koha"
should produce:
Authentication failure:
    500 Can't connect to admin.kobe.local:80 (Bad
    hostname)

Works as described and gives better error messages.
There are some warnings output when running the script before
and after applying the patch.
