GenericIE: New flashplayer case: config file (solution inside)

[maximeg]

As @phihag fixed a previous bug report #734 using :

webpage = self._download_webpage(url, video_id)

it made me think about a case.

Test case:
http://www.nokenny.com/comment-ne-pas-casser-une-table.html

This webpage contains :

...
<embed src="http://www.nokenny.com/player.swf" width="100%" height="400" allowscriptaccess="always" allowfullscreen="true" type="application/x-shockwave-flash" flashvars="config=http://www.nokenny.com/v/comment-ne-pas-casser-une-table&image=&logo=&displayclick=play&autostart=1&plugins=fbit-1,tweetit-1&controlbar=bottom&frontcolor=&lightcolor=&backcolor=FFFFFF"></embed>
...

And the config file (http://www.nokenny.com/v/comment-ne-pas-casser-une-table) contains :

<?xml version="1.0" encoding="ISO-8859-1"?> <config>
    <file>http://www.nokenny.com/FLV/upload_flv/video_15644_1343987924.flv</file>

So here the code :

        # Start with something easy: JW Player in SWFObject
        mobj = re.search(r'flashvars: [\'"](?:.*&)?file=(http[^\'"&]*)', webpage)
        if mobj is None:
            # Broaden the search a little bit
            mobj = re.search(r'[^A-Za-z0-9]?(?:file|source)=(http[^\'"&]*)', webpage)
        if mobj is None:
            # Broaden the search a little bit: JWPlayer JS loader
            mobj = re.search(r'[^A-Za-z0-9]?file:\s*["\'](http[^\'"&]*)', webpage)
        if mobj is None:
            # Broaden the search a little bit: Flashplayer calling a config file
            mobj = re.search(r'[^A-Za-z0-9]?config=(http[^\'"&]*)', webpage)
            if mobj is not None:
                config_url = compat_urllib_parse.unquote(mobj.group(1))
                config_page = self._download_webpage(config_url, video_id)
                mobj = re.search(r'<file>\s*(http[^<\s]*)\s*</file>', config_page)
        if mobj is None:
            self._downloader.trouble(u'ERROR: Invalid URL: %s' % url)
            return

Again, I let you evaluate this, my python skills improved by 300% just by writing this :)
