The main item in this commit is showing of errors with a file context when running `hugo server`. This can be turned off: `hugo server --disableBrowserError` (can also be set in `config.toml`). But to get there, the error handling in Hugo needed a revision. There are some items left TODO for commits soon to follow, most notable errors in content and config files. Fixes #5284 Fixes #5290 See #5325 See #5324
