Moved the Tern.js work and acorn-qml into the Qt Core plugin rather than
in a separate plugin. Added walk.js in order to facilitate walking the
QML AST by acorn-qml. Changed a few things in index.js and inject.js
for acorn-qml in order to get it working in a browser environment.
Added a tern-qml webpage demo which doesn't do much for now.
