Only show hostname (not FQDN) as header
Updated Domino DB Browser demo app to use a Page_Count of 100 when calling GetCollectionEntriesTreeData. 100 is the default max page size on Domino servers, so I didn't go higher than that.
Fixed parsing of Category (Grouping) nodes in a document set. Since Category names come from arbitrary fields in an NSF database, only the sequential number of the category is shown in the zTree display.
