Text tokens now accurately reflect their content's exact position
in the original template.

Also, changed order of arguments to internal render function.

Fixes #207 #210

This is a strict port of the existing process - there are many opportunities for optimization based on this.

Also, allow partials to be passed to the function that is returned
for pre-compiled templates. This makes the API more consistent all
around, but comes with the caveat that renderers are much more
aggressive at caching. Now, any time a template or partial is
compiled with the same name as a previously compiled template the
cached version is used.
