This way we can have attachment of fairly arbitrary size (which should
be extremely useful for long libdivecomputer logs). This isn't quite as
intuitive as what we did before - the user needs to pick an email app to
share with), but that doesn't seem too bad - and also... this way they
can share logfiles via Dropbox or analyze them in other apps).
If the file share fails for some reason, we fall back to the old method
with passing the combined logs as body to the support message.
As an implementation detail this keeps the correct path for the app log file around
(this was stupidly overwritten before).
