Bug 28375: Inefficiencies in fetching COinS

This patchset adds an 'interface' parameter to XSLTParseForDisplay to avoid fetching
coins when not needed

Additionally we move some logic from the scripts to searchResults to avoid an extra fetch fo the biblio object

To test:
1 - Enable  COinSinOPACResults syspref
2 - Also enable  OPACShowOpenURL  and  OPACOpenURLItemTypes  - adding an itemtype that you can find
3 - Perform a search on the OPAC and confirm coins are included and openurl shown
4 - Perform a search on staff client and confirm openurls do not show
5 - Apply patch
6 - Results should be the same
