Work on web api & apps based on the C run-time system

+ PGFService.hs: add command c-grammar, include probability in parse results
+ js/gftranslation.js: add start position and limit parameters, return more
  info to applications
+ Simple Translator: show two wide coverage translations
+ Wide coverage demo: show parse tree and probability (intended as grammar
  debugging aids)
