Improve error messages, esp. when the server is running

* Add file context to minifier errors when publishing * Misc fixes (see issues) * Allow custom server error template in layouts/server/error.html To get to this, this commit also cleans up and simplifies the code surrounding errors and files. This also removes the usage of `github.com/pkg/errors`, mostly because of https://github.com/pkg/errors/issues/223 -- but also because most of this is now built-in to Go. Fixes #9852 Fixes #9857 Fixes #9863
