UI: Prefix routes with /library/... so that 404 can be returned for non-existing assets

[benmccann]

During development I was requesting a JS file that did not exist. However, it took me a very long time to figure this out because the browser was returning a 200. I thought I had Babel configured wrong or something because it kept telling me I had a malformed JS file. In reality it was returning HTML inside my JS

Routing is performed on the client. There is no simple way the server may know what routes exist in JS - and we can't afford to add much more complexity right now.

We may of course implement a 404 page in JS saying "No found, click here to return to home" instead of redirecting to home straight away. Not sure how much value this provides to our users though.

Ah, that makes sense. While we can't do it for a generic route, we might be to implement a 404 just for non-existent .js and .css files

It looks like this would be handled here:

router.NoRoute(func(c *gin.Context) {
