Copy head (r256279) to stable/10 as part of the 10.0-RELEASE cycle.

Approved by: re (implicit)

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.

Fix two cut'n'paste'os which violated format of NLS catalogs

Update FreeBSD translations to match 1.4.1 (actually just copied Enslish
messages as I don't know de, pl and fr).

$Header$ -> $FreeBSD$

Change message 103, trailing \n is not needed when using errx(3).

Translated too much of it.

Polish message catalogs for ee.

Still buggy. Help messages and command names are not in sync,
eg. 'quit' <-> 'KONIEC'.
