FileSaver window.saveAs shim
// window.saveAs
// Shims the saveAs method, using saveBlob in IE10.
// And for when Chrome and FireFox get round to implementing saveAs we have their vendor prefixes ready.
// But otherwise this creates a object URL resource and opens it on an anchor tag which contains the "download" attribute (Chrome)
// ... or opens it in a new tab (FireFox)
