admin: bump version numbers
align full.xsl and fullSplit.xsl - now identical
remove `htmlFullSplitTxr` (now simply `htmlFullTxr`)
remove now obsolete `fullSplit.xsl`
protect against `NoneType` in `cleverTitleCase`
add fallback for `titleFromRecordIdentifier()`

Previously `titleFromRecordIdentifier()` failed when viewing a
Record that had been loaded but not indexed, due to dependence on
the sort value in the title Index. Now falls back to extracting the
title from the Record in question (this is slower than fetching sort
value from the title Index hence why it is a fallback option.)
remove potentially duplicate display of did/note
additional XSL protection for `@audience="internal"`
