Title: Attach template source to returned function.

Exposing the source of the template function makes it trivial to precompile templates server side. This yields several benefits:

* Templates are precompiled with the same code they are compiled with on the client.
* Break points can be set when debugging.
* When errors occur, a stack trace and line number are provided.

I also attempted to make some of the variable names more expressive. Feel free to bikeshed them.
