Support any HTTP method
It's now possible to use redbean Fetch() with arbitrary HTTP methods, e.g. LIST which is used by Hashicorp. There's an eight char limit and uppercase canonicalization still happens. This change also includes a better function for launching a browser tab, that won't deadlock on a headless workstation running Debian. Closes #1107
