Title: enable ace autocomplete

* enable basic and live autocompletion in the ace editor
* add a "completer" for APIs that we expose per-level
* tweak blockCount element when hidden to be "display:none" instead of hidden - fixes centering of neighbor
* make breakpoint blue semi-transparent, allows other ace gutter elements to appear through the breakpoint
