Added the loader script

Good to have this versioned, for reference if nothing else.
Committed /u/Zephymastyx's fixes.

New twitch chat broke the old script. Zephymastyx provided a fix. There is some aesthetic work to be done but this fixes the functionality.
Added "whitney" to misty filter list.
Added "milk" to the misty filter. ffs....

Detect which version of the chat we are using

The new chat filter doesn't work for the old chat. Ideally we would have
one single filter for both, but for now we are going to have to live
with this hacky solution.

We have to test for the new chat filter with a DOM element, and I don't
have the new chat, so I picked button.viewers. Not sure if that is the
best choice but that's one of the few unique things I see in the new
filter.
Fix bug in greasemonkey
