[CS2] Fix #1768: Ignore space after ::

[GeoffreyBooth]

Fixes #1768. So as Array:: isArray becomes Array.protoype.isArray, now Array:: ["isArray"] becomes Array.prototype["isArray"].

I guess this is fine.

(Just a random piece of trivia: Function.prototype is actually a ... function! A noop function, to be precise. Paste Function.prototype() in the console to try it out!)

[GeoffreyBooth]

Are you sure?

➜  ~ node -e 'console.log(typeof String.toString)'
function
➜  ~ node -e 'console.log(typeof String.prototype)'
object

EDIT: Looks like Function.prototype is a function, but for any other core object I try—String.prototype, Array.prototype, Date.prototype, Buffer.prototype—the prototype is always an object.

@GeoffreyBooth Yep, that's the way it is. Strange feature, huh?
