Fix Bug 964091, precompile nunjucks templates always, remove pointers bit as it is strangely having the opposite effect

@erikrose r?

After or before starting the server in the VM just run

    grunt dev

This will precompile the nunjucks templates and start the watch process that will, upon a change to any of the templates, rerun the nunjucks target.

From what I can see the changes in this PR is making a definite difference but, I am only testing against files of ~25,000 lines.
