Change relative paths to root relative paths in stylesheet and script links

[funnicus]

Hey!

I've enjoyed the GoTHH stack so far! However, there might be a problem for people who want to expand the template app further in their own projects.

Problem: Relative paths in the stylesheet and script links cause the app to load CSS and JS files from incorrect paths when fetching resources in routes of 2 segments or more (so /a/b/). This leads to CSS and JavaScript not working on those pages. Illustration below (file fetched from /activities and not /).

Suggested fix: Easy fix would be to change the paths from relative to root relative paths. This fixes the problem.

Example:

Change this
<link href="static/css/style.css" rel="stylesheet" type="text/css">
To this
<link href="/static/css/style.css" rel="stylesheet" type="text/css">
