[PATCH 1/2] vim plugin: Implement show_view_all_mime_parts

[Ryan Harper <rharper@shake.ath.cx>]

Implement mime attachment viewing in the vim plugin via
notmuch show --format=text parsing for attachment segments.
Extract the part ID, filename, and content-type.

Storing this in a dictionary for use later when implementing
attachment saving.
