Remove dependency on window.event in ListView
Remove dependency on window.event in ListView

Fixes Microsoft/monaco-editor#371.

The `event` property of Window is [nonstandard] and isn't supported by Firefox,
breaking some of ListView's event-handling behavior.

I checked for places where VSCode depends on `window.event` by removing it from
`lib.d.ts` and building from scratch; the references in ListView were the only
ones I found in `src/vs/base/browser`. There are also some references in
non-browser parts of the codebase, but I assume that's fine since they work in
Electron.
