Summary: email.Charset.py CODEC_MAP no longer requires 'japanese'

Initial Comment:
The commonly used JapaneseCodecs no longer requires
'japanese' prefix in codec specification.  On the other
hand if a user install CJKCodecs instead of
JapaneseCodecs, 'japanese' prefix cause error.

This was already fixed in email-3.0 (Python 2.4) but
should be fixed in email-2.5.x if we want to support
mailman-2.2 for Python 2.3.

It looks like 'korean' can also be stripped.

See attached patch.

The attached patch addresses the issue both in this issue
and in 1409544.  It's a bit more extensive because it tries
to figure out whether the Japanese and Korean codecs are
available under their Python 2.4 names or under their old
names.  I've run this test under all Pythons from 2.1 to
2.5, albeit without the third party codecs under anything
before 2.4.

Looks like we should retain CODEC_MAP in order to properly
encode Japanese text into iso-2022-jp (canonical japanese
message charset).  We need lines like this:

CODEC_MAP = {
    'euc-jp':      'euc-jp',
    'iso-2022-jp': 'iso-2022-jp',
...
    'us-ascii':    None
}
