sterni 8e156e6b86 feat(sterni/mblog): convert apple note mime msgs to html
For now mblog only contains the mnote-html executable which takes a mime
message from a maildir and prints the equivalent HTML fragment to
stdout. It is intended to work with the mblaze(7) utilities,
i. e. mnote-html resolves all `object` tags to proper `img` inclusions
with the correct filename, so mshow(1)'s -x version can supply the
needed image files. A note created using Apple's Notes app (tested with
the iOS version) can be converted in a viewable HTML file like this:

    $ mnote-html path/to/msg > fragment.html
    $ mshow -x path/to/msg
    $ cat <(echo "<!DOCTYPE html>") fragment.html > document.html
    $ xdg-open document.html

Note that only the limited feature set of Apple Notes when using the
IMAP backend is supported. The iCloud-based one has more (quite neat)
features, but its notes can only accessed via an internal API as far as
I know.

This CLI is a bit impractical due to the big startup overhead of loading
the lisp image. mblog should be become a fully fletched static site
generator in the future, but this is a good starting point and providing
the mnote-html tool is certainly useful.
