Bug 4497: Make tabs for managing suggestions translatable

This patch makes the tabs on the manage suggestion page translatable.

To test:
- Create some suggestions in intranet or opac and manage them to make the
different status tabs appear: accecpted, pending, checked, rejected
- Apply patch, run 'perl translate update <languagecode>'
- Check po file for string '%s %sPending %sAccepted %sChecked %sRejected %sAvailable %sOrdered%s %s%s %sNo name%s (%s)'
- Translate it, save and run 'perl translate install <languagecode>'

Tabs should now appear translated.
