Bug 8732: Allowing biblio level itemtypes to display instead of MARC ones

Bug 8732: Allowing biblio level itemtypes to display instead of MARC ones

This patchset adds a new syspref: BiblioItemtypeInfo

If you set BiblioItemtypeInfo to Koha, you will see the Koha
record level itemtype info. This info is also shown if item-level_itypes
is set to biblio

Display of icons are controlled by
noItemTypeImages/OpacnoItemTypeImages

Material type display is controlled by DisplayIconsXSLT/DisplayOPACIconsXSLT

To test:
 1 - Apply patch
 2 - Update database
 3 - Do an opac search and view results
 4 - Switch pref to 'Koha' and refresh
 5 - Note itemtypes appear
 6 - Click in to a record details
 7 - Note you see itemtype and icon
 8 - Switch the pref
 9 - Note you don't see record level itemtype and icon
10 - Repeat in staff interface
