mml-attach-file always at the end of the buffer

[SF]

Hi,

For some time already, I wanted to extend mml-attach-file, so it always 
attaches the file at the end of the buffer.

I'm sure this could also be done with a defadvice to move to the end of the 
buffer and then return upon exit, nevertheless here's my solution for it, since 
I haven't tinkered yet a lot with defadvice.
