hard coded node_modules

[kiwina]

HI,
it be nice to see the hard node_modules directory removed.
Simply if i like to change more than just variables on the theme and copy the theme-default to some other place node_modules is still added to my custom path

$ gulp
[13:24:27] Local gulp not found in ~/main/vue/theme-default
[13:24:27] Try running: npm install gulp

why???
