flush temporary attachment files before viewing

I was having problems with the temporary attachment files being empty
when external programs (vim and w3m, and using system(), so blocking)
opened them from my mime-view hook. Flushing the content before yielding
in Attachment#write_to_disk fixes the problem for all the cases where I
encountered the problem.

Merge #183: Wrap form_driver_w for wide char input

form_driver does not work correctly on all systems (specifically Mac OS X),
it is difficult or impossible to determine whether the input char is a
char or key code resulting from a char sequence in a multibyte char.

If no form_driver_w is present we fall back to form_driver.
form_driver_w is included in ncursesw-1.4.2 with the Ncurses 5.9 20131207
patchlevel.

in all other respects.

Small fix to "correctly" parse PGP inline signed mails by
(presumingly) GPGMail 1.4.1

Content-Type: application/pgp; format=text; x-action=sign

and inline separators as:

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

<body>
-----BEGIN PGP SIGNATURE-----

<signature>
-----END PGP SIGNATURE-----

former version only tried to decrypt body, which in this case obviously
fails.
