Hammer.js: Make hammerjs server friendly

[elmerbulthuis]

When redering views on a server (like in a universal / isomorphic application) we do not have a window or document instance. This will result in an error in hammer.js.

Ofcourse hammer.js has no use in a server environment, but hammer.js should not throw an error when it's only being included (via require, or import).

This here, line 2643 in the hammer.js file:

})(window, document, 'Hammer');

is causing trouble, window and document are not defined in a server environment.
