Make javascript gobject bindings independant.

Moving the bindings into a single file makes them independant
of addons and midori, requiring only JavaScriptCore and GObject.

This allows for standalone scripts to run independant from
Midori itself. Also extensions will run independant from a
browser instance.
This change removes the 'midori' object.
