issue:
--cname was broken, 404.html wasnt created

error message:
Error when trying to deploy:
{ [Error: ENOENT: no such file or directory, open 'X:\X\\your-angular-project\dist\your-angular-project\CNAME']

resolution:
workspace.root was "normalized" (Windows drivers are replaced with `/X/`, where X is the drive letter)
but this was breaking with fse.writeFile() and fse.copy(), used asWindowsPath() to fix that again

question @mgechev
Is there some better / recommend way to solve this?

fixes #61
