External Libraries: Update Masonry shim to prevent error using isAnim…

…ated option

The isAnimated option throws an error and causes Masonry to stop functioning. Masonry.prototype.options is no longer defined in 3.3.2, this.options is and does the same. Masonry was updated to 3.3.2 in [37891].

Reported upstream: desandro/masonry-v2-3-shim#1
