Make preferred directory structure for Autofill configurable (#660)

Some users keep their password files in a directory structure such as:
/example.org/john@doe.org.gpg
while others prefer the style:
/example.org/john@doe.org/password.gpg

This commit adds a setting that allows to switch between the two. All Autofill
operations, such as search, match, generate and save, respect this setting.

Note: The first style seems to be the most widely used and is therefore kept as
the default. The second style is mentioned on the official Pass website at:
https://www.passwordstore.org/#organization
