(plugins) stream, url_info_finder, wsserver

wsserver have a hard limit of 100 connections (should be changed to max
x/IP). Also logging.

url_info_finder each received message now starts a new thread. So it
can't be locked by long dns lookups etc.
now also loads bigger chunks to find title (~32kb, still to
small for some websites like amazon, who has like 1MB of html/JS before
the title in the header).

stream - needs some general work still. Should use settings.py for the streamer-list.
