build:devserver and start:devserver fail to launch on windows after upgrading to 0.3.0

[IBwWG]

This is separate from trying to run production, which is still broken, but was before 0.3.0 as well: #7 (comment)

npm run build:devserver had been working before 0.3.0 (whatever was current yesterday morning worked.) Now it gives this:

> NODE_ENV=devserver webpack-dev-server --config webpack.devserver.config.js --c
ontent-base public/dist/ | grep -v  "\[built\]"

'NODE_ENV' is not recognized as an internal or external command,
operable program or batch file.

I get similar results trying to run npm run start:devserver, which also had been working prior to 0.3.0.

npm run win:build:devserver should be used on Windows.

README and FAQ updated in 0.3.1.
