Falied Install on Windows

[RoboticMind]

When I run the command npm run build-prod here is the output:

> GridcoinWebClient@0.1.0 build-prod [REDACTED] > NODE_ENV=production webpack

'NODE_ENV' is not recognized as an internal or external command, operable program or batch file. npm ERR! code ELIFECYCLE npm ERR! errno 1 npm ERR! GridcoinWebClient@0.1.0 build-prod: `NODE_ENV=production webpack` npm ERR! Exit status 1 npm ERR! npm ERR! Failed at the GridcoinWebClient@0.1.0 build-prod script. npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

I cannot get the Gridcoin-Web-Client to properly install on Windows

Hi RoboticMind,

Windows does not accept the syntax used by Bash for setting environment variables, which is why this is failing. I was able to build on windows by running the following commands:

> set NODE_ENV=production
> .\node_modules\.bin\webpack

To run it, you can use the same syntax:

> set NODE_ENV=production
> set GWC_PORT=8080
> set GWC_HOST=127.0.0.1
> node src\server.js

I'll update the readme with this information.
