minibar+syntax editor integration, work in progress 2

+ Transfer current astract syntax tree when activating the syntax editor
  from the minibar.
+ Add options to start the minibar with given input. You need to include
  the current grammar url, the current language and the input, like this:

    initial_grammar: "/grammars/Foods.pgf",
    initial: { from: "FoodsEng", input:["that","fish","is","fresh"]}

+ Fix a style sheet clash.
