Sam 7c5a448f63 PERF: remove 10-20ms of work from every page view
<%  s=Time.now;

main_app.categories_path
main_app.guidelines_path
main_app.tos_path
main_app.privacy_path

p (Time.now-s)*1000%>

Returns 10-20ms consistently on i7-4770k, on shared hosts the cost
could easily reach 40ms

This code simply calculates the strings

/categories
/guidelines
/tos
/privacy

It is ludicrous to spend this enormous amount of work just to calculate
4 strings.

I do not know if this is something specific about Discourse or a bug in
Rails (I tried without the main_app prefix and got similar results),
regardless we can got to avoid these _path APIs for now

Discovered this when running a flamegraph on our home page.
