Use Braille Utils v1.2.0
Bugfix: liblouisutdml transformation failed when path to tables contained a space
Remove weird duplicate namespace declarations from css:apply-stylesheet output
liblouis-formatter: put louis namespace declaration on root element
Added pef-saxon with XSLT bindings for Braille Utils (currently only pef:encode)

Make the PEF preview look exactly like the BRF output (using pef:encode)
