feature request: expose render context

[atk]

One of the rather nice features of janl's implementation of Mustache in JS is that the context is exposed, so it can be overwritten in order to provide certain filters/defaults/features.

It can be exposed quite easily by changing function walkToFind(context, name) in render.js to render.context = function(context, name).

I would really like to see this in Mu. Thank you for your time.
