Fabio Alessandrelli 55f04952c5 [HTML5] Add JavaScriptToolsEditorPlugin.
A new editor plugin, specific to HTML5, that provide some extra features
needed to make the editor usable on that platform.

For now, it adds a "Download project sources" option in the "Tool" menu,
so the user can download the work done as a zip file (from the browser
storage).
