Get pancake working in Windows

[dominikwilkowski]

Windows is the new IE for node devs.
Areas that need attention from looking at initial tests:

• The bash script in each module won't work naturally
• Spawning new processes don't go down as they should. Need to look at that
• The Sass paths need to be adapted to each os
• Get folder creating to work

try cross-env npm plugin

That's all good. Thanks @elisechant

The only two problems I ad was getting rid of the bash script which is done already and spawning a child process which is easily done with:

const npmVersion = parseInt(Spawn('cmd.exe', ['/s','/c','npm', '-v']).stdout);

Sniffing OS is done with:

const isWin = /^win/.test(process.platform);

(can't use os.platform() as we support node 5)
