Title: Dev flags: merge maps with same name defined in different config files instead of overwriting

@gaurave

This will be used shortly for advanced configuring of Bower.

E.g.
app.json:
"some-map": {
"a": "aa"
}

.spark.json:
"some-map": {
"b": "bb"
}

will result in:

"some-map": {
"a": "aa",
"b": "bb"
}
