Added a new top-level stylesheet module, chunk-changebars.xsl, to be

used for generating chunked output with highlighting based on change
(@revisionflag) markup. The module imports/includes the standard chunking
and changebars templates and contains additional logic for chunked output.
See FRs #1015180 and #1819915.
