Promise.done is deprecated.

Atom now uses ES6 Promises instead of Q. Call promise.then instead of promise.done ``` Promise.done (/Applications/Atom.app/Contents/Resources/app.asar/src/atom-environment.js:1148:5) Object.toggle (/Users/dev/.atom/packages/atom-html-preview/lib/atom-html-preview.coffee:108:10) atom-workspace.subscriptions.add.atom.commands.add.atom-html-preview:toggle (/Users/dev/.atom/packages/atom-html-preview/lib/atom-html-preview.coffee:57:26) CommandRegistry.handleCommandEvent (/Applications/Atom.app/Contents/Resources/app.asar/src/command-registry.js:260:29) (/Applications/Atom.app/Contents/Resources/app.asar/src/command-registry.js:3:61) KeymapManager.dispatchCommandEvent (/Applications/Atom.app/Contents/Resources/app.asar/node_modules/atom-keymap/lib/keymap-manager.js:580:16) ```
