refactor: move supported views array to file

[ungoldman]

Tried moving supported views array to file as suggested in #146 (comment)

One thing worth noting: in lib/browserify-transform.js, choo is included in the list, whereas in babel.js it is not. My feeling is that it's not needed (choo/html is included in both), but I'd like confirmation of this from a maintainer before moving forward.

Tests suggest my assumption was wrong :)

Will take another look later, as I'm on a desert island for a week! Please feel free to correct my PR and merge it in my absence. May just be that adding choo back does the trick.

I believe the 'choo' entry was intended for old choo, when you'd do

choo.view`<div />`

aye, enjoy the island :D i will add it back for now, we can remove it in a major release though
