Two issues on Windows - reflect-metadata missing and client app crash #185

There's two issues with windows.

1. webpack complained that it couldn't find reflect-metadata. I removed the import of reflect-metadata and then webpack completed without errors. I have no idea if this is correct fix.

2. The counter's increment button isn't working. Turns out the issue is that precache from server is displaying pages, gives illusion of working, but client app crashes. This can be proven if you remove precache from tag and run. "Loading..." appears but the webpages are never shown. I have no idea what's broken. Maybe related to first issue?

Works fine using Ubuntu 16.04.
