Mod to handle gzip encoded pages + timeouts

[GoogleCodeExporter]

Occasionally the 4od site will send a gzip encoded page or will timeout.
The following change will try the site 3 times, add a 20 second timeout and 
handle the gzip issue:
file: geturllib.py
replace _GetURL_NoCache with:

def _GetURL_NoCache( url ):
        import urllib2,time,socket,gzip,StringIO
        socket.setdefaulttimeout(20)
        x=''
        try: 
                x = urllib2.urlopen(url)
        except ( urllib2.HTTPError, urllib2.URLError ) as err:
                try: 
                        x = urllib2.urlopen(url)
                except ( urllib2.HTTPError, urllib2.URLError ) as err:
                        try: 
                                x = urllib2.urlopen(url)
                        except ( urllib2.HTTPError, urllib2.URLError ) as err:
                                print err.reason
        #x = urllib2.urlopen(url)
        try:
                if x.info()['content-encoding'] == 'gzip':
                        gzipper = gzip.GzipFile(fileobj=StringIO.StringIO(x.read()))
                        x=gzipper.read()
                else:
                        x=x.read()
        except KeyError:
                x=x.read()
        return x
