Make Javascript and Stylesheet entries optional

[StallionV]

I really liked the simplicity and would want to use it. But my structure is different.

Currently the below entries are Mandatory in package.json.
"frontend": {
"name": "Flux",
"javascripts": "./src",
"stylesheets": "./"
}
But if your structure is different how do you use it.
I would prefer if along with the name the only thing I can enter is "source": "./src" or similar.
This will pick up my complete structure instead of segregating it by JS and CSS
e.g.
"frontend": {
"name": "Flux",
"source": "./src",
}
