streamlining as suggested by Dimitris
Few more language tweaks

language config + dash templates resolution
even more languages
adding an "xxx onward" construct

only few occurrences in English but common in Spanish
add standard splitPropertyNodes mechanism

ignores everything following. This "mapping" is de facto a parser and
should handle lists as other parsers do.
