tsc lib config to include MS DOM

[gforceg]

TypeScript Version: 2.1.5

I wish I could say something like this in my tsconfig.json:

"lib": [ "es2015", "dom", "dom.microsoft"],

and then I could compile my source without error when it looks like this:

let buffer = 'the buffer you wish to copy'
static POS = !!window.clipboardData

// if IE11, copy buffer to clipboard
if (POS) { window.clipboardData.setData('Text', buffer) }
// if other browser, copy buffer to clipboard
else { Clipboard._data = buffer; document.execCommand('copy')}

Just declare the extras that you need.
