Fixed error when DOC file was actually text

Better handling of xb and other odd ANSI filetypes
Noting new handlers - chafa, ansilove, and node-iconv

Please note that as I've been adding new filetypes to handle, the dependencies have increased for my default handlers. If you are upgrading on a Debian system (and probably Ubuntu) you can issue:

sudo apt update;sudo apt-get install fzf awk sed file mysql sqlite3 pandoc lynx wv unrtf pdftotext bat dtrx csvtool gnumeric w3m libfile-mimeinfo-perl ansilove chafa node-iconv

to snag them all

Added ANSI/ASCII art viewing

Drop-in with URLPortal

If you would like to streamline and consolidate your mailcap style experience, you can use showdocs in place of your regular mailcap file.

If offered an URL, showdocs will follow any redirection (if muna is installed and in your $PATH). If there’s a filename with extension already there, it will grab it and process the file locally (using URLPortal if needed). If there is not a file extension specified on the URL, it will download the file, then use mimeinfo to try to figure out what it is, rename it appropriately, and process it locally (using URLPortal if needed).

This means that you can pass filenames or URLs straight to showdocs and use the same flow.

I’m sure I’ve missed some major mimetypes that are odd (like how “vnd.ms-asf” is a mimetype for WMV files), please let me know what I’ve missed!
