add js_extensions_path...

add js_extensions_path serves files in `IPYTHONDIR/js_extensions` at `/js_extensions`. This is a location for users / devs to drop-in frontend customization as js modules, css, etc. The model is very much like the extensions dir (hence the name) - it's a location made available, but not loaded by default. You can load things from there with require, etc. It's a configurable search path, just like static. This way we can define a system-wide location at a later point (/usr/share/ipython/js_extensions?) and still have user installs.

      This uses the ETS 4.0 selection pattern of:

      PySide first, PyQt with API v2. second.

      Do not use this if you need PyQt with the old QString/QVariant API.
