xtensions and XR applications

Extension authors can write most of their application in JS. However, they may still need the ability to interact with native code. This is important so that they can use
* precompiled external libraries (imagemagick)
* perform operations in native code which would be too slow in JS
Both of these use-cases can and should be solved with a FFI library which is exposed to JavaScript. See mfinkle's post about an early prototype based on python ctypes. Solutions such as SWIG may also be useful for scripting more complex C++ APIs.
