Wez Furlong 42bf5c5e61 docs: adjust reference to improve search terms
We've been hoping that mkdocs-material will ship the much anticipated
search enhancements for some time, but it's time to recognize that
we need to do something to improve the search results with how
things work right now.

This is a big commit that changes the titles of the various pages
from the code-annotated synopsis to just the name of the function.

This makes it much easier now to match things like `kumo.reject`
directly, but `reject` remains awkward to find.

I think this is the best that we can do at this time.

A few functions have been annotated with the `status: deprecated` to
show as deprecated in the toc/nav (shows with a little trash can next
to the name).

append_text_html

message:append_text_html(content)

{{since('2024.06.10-84e84b89')}}

Identifies the primary text/html part of the message, decodes its transfer encoding, and locates the closing "</body>" or "</BODY>" tag. If the tag is found, content is inserted ahead of it. If no body tag is found, appends the content string to the part. The part is then re-transfer-encoded and the message data is updated.

This is useful for example to add a tracking pixel into the message:

umo.on('smtp_server_message_received', function(msg)
  local my_tracking_link =
    '<img src="http://10.0.0.1/img_tracker.jpg" alt="open tracking pixel">'
  msg:append_text_html(my_tracking_link)
end)
