Summary: readline not implemented for UTF-16

Initial Comment:
The StreamReader for UTF-16 (all three of them) doesn't 
implement readline.

I've attached a monkeypatch to get readline support for utf-16 codecs..

import utf16reader
utf16reader.install()

It can be trivially inserted into the utf16 encodings implementation.. it 
would be really cool if someone would audit the implementation and 
sneak it in before Python 2.4 :)

I don't need it enough to write a patch, but this is what I used instead.. 
and it seems like it might work:

    try:    
        for line in inFile:
            tline = translator(line)
            outFile.write(tline)
    except NotImplementedError:
        BUFFER = 16384
        bytes = inFile.read(BUFFER)
        while bytes:
            lines = bytes.split(u'\n')
            bytes = lines.pop()
            for line in lines:
                tline = translator(line)
                outFile.write(tline)
            newbytes = inFile.read(BUFFER)
            bytes += newbytes
            if not newbytes and bytes:
                bytes += u'\n'
