[DP] Rename datapackage.json to package.json in Data Package

[rufuspollock]

Reasoning: we already follow CommonJS package spec very closely and this would allow us to leverage the npm (node package manager) ecosystem directly (a big win!)

See for further discussion this thread: openknowledge-archive/datapackage.js-deprecated#3

I'm still a bit mixed in my feelings here. Changing datapackage.json to package.json is a pretty major change in the spec. The major reasoning is the ability to reuse npm directly but I'm not totally sure yet how much we will directly reuse npm (e.g. we may reuse parts but probably with a bit of modding ...)

Pros to package.json:

• direct compatibility with node and npm

Cons:

• We don't have something distinctive
• Its a change from current spec
• Possible conflict where you have a repo that is both a node package and data package (seems a very minor consideration)

@sballesteros @paulfitz love your thoughts here ...

WONTFIX. We have agreed to keep datapackage.json, reasoning being:

• we won't directly reuse npm (though we will reuse concepts)
• default would be no change
• we can then search for datapackage.json etc
