feat: add AoT compilation with webpack

[sis0k0]

Implements #213

Looks good. One minor note: on iOS when I run the app with webpack bundling the status bar code doesn’t work for some reason.

I don’t think that should hold this up as it’s rather trivial (and works fine on Android), but I thought I’d mention it in case if you have any ideas what might be going on.

Out of curiosity, why is this necessary?

Here’s what I see on iOS.

The white status-bar turned out to be caused by webpack not handling the ~ symbol in @import url("~/platform.css");.
@hdeshev will investigate if we can support that, but for now the workaround is just to use "./platform.css" instead.
