Changeset 26023 for main/trunk/greenstone3/web/interfaces/default/transform/gslib.xsl

Message:

1. Fixing the java code to handle gsf:equivlinkgs3 again. The code had recently been changed to remove the gsf:meta attribute of multiple=true to use attribute pos=index|first|last instead. But when multiple=true in the past, _all_ would be prefixed to the metadata_sep and metadata, and this still needed to be processed. 2. Added the XSLT to deal with gsf:equivlinkgs3 into the default skin (previously this was only added into gs3-library which has now become the basic skin). With changes 1 and 2, the parts of the DSpace tutorial which deal with equivlink now work for GS3 (again).
