[NLRS] Let's give this a try for a while. Now .jpg's and .pdf's are allowed as ATTACHMENTS

[Bruce Richardson]

I'm pretty sure they won't work as embedded html.  But if you "attach" them,
they should work.

Let's give it a try and if users (you) find it not working or annoying, let
me know.

1 MB is still the size limit for the present.
