lei import: add IMAP and (maildir|mbox*):$PATHNAME support

This makes "lei import" more similar to "lei convert" and
allows importing from disparate sources simultaneously.

We'll also fix some ->child_error usage errors and make
the style of the code more similar to the "lei convert"
code.

v2: fix missing requires
