Fix for Issue 255

Fixes https://github.com/andypike/lagtv/issues/255

Adds lagtv stream, speeds up tests, cleaned up some old stream code, more tests for the streams. This will need to have pretty icons instead of my lame CSSed spans, but I cannot create art with this brain of mine, so I'll leave that to somebody more talented than I.

I believe this should be rebased off of 1.3.0 already.
