    verification and other features.  Thanks: Steven Murdoch.
    -fix missing plaintext versions of documentation.  Thanks: Osamu Aoki.
    -fix "Header instance has no attribute 'strip'" error which cropped up
    in some configurations.  Thanks: Krzysztof Warzecha.
Added passwordeval option and documentation.

Removes need for plain text password in the getmailrc file. Instead of "password"
option "passwordeval" option can be used.

For example:

passwordeval = gpg -d gmail.gpg

The value of the "passwordeval" option is run and the output is used as the
password. If password cannot be found from the output, then password is prompted
from the user.
