LastFM: add experimental YouTube link fetching for 'np'

Browse Source 
Essentially, my reimplementation of krf/supybot-lastfm#8. Instead of using YouTube's API (which requires API keys and all that), this performs web search on site:youtube.com using the DDG (DuckDuckGo) plugin in this repository. The advantage to this is that it's simpler to set up, but results may not always be the most accurate / relevant.

This behavior can be turned on by setting supybot.plugins.LastFM.fetchYouTubeLinks to True - it defaults to off since this is experimental anyways. The DDG plugin needs to be loaded too for this to work.

Also, only bold the album/artist/track data during output formatting, NOT before (this screws up searches with all the \x02's).
