rethink the way makeDescription works, and change some test results as fallout

the template makeDescription was called often. now re-expressed as a
function. take the opportunity to make the teito* scripts support a
--lang switch, and remove a file (odds.xsl in common) which is folded
into functions.xsl and teiodds.xsl
do clang and documentationLang parameters are also to set by --lang flag on teito*
