Copy head to stable/9 as part of 9.0-RELEASE release cycle.

Approved by: re (implicit)

Import ee 1.5.2 into HEAD.

PR: bin/145921
MFC after: 2 weeks

Update ee(1) in the base system to version 1.5.0.

This version is now licensed under a 2-clause BSD license, instead of
the Artistic license. I've reverted a lot of local modifications we made
to ee, because they have been integrated upstream as well.

Only local modifications include:

- $FreeBSD$ ID.
- Pathname to init.ee.
- catopen() call, to honor LC_MESSAGES instead of LANG.

To keep SVN happy, I'm putting an application/octet-stream mime type on
the KOI8 translations.
