This feature detect shows whether the new collections constructors for ES6 are supported: Map, Set, WeakMap and WeakSet.
Chrome implements all 4, but hides 2 behind a flag. Firefox implements 3.
Polymer requires WeakMap, so detecting this may allow us to skip loading the poly-fill in upcoming browsers.
Part of #1170.
@jokeyrhyme somehow I missed this, do you wanna rebase off of master?

@patrickkettner thanks, that's really life-affirming of you. :) I think that you are also a really cool dude. :)
