Update project.json to use array for code, exclude, resource and shared

[keichinger]

Browsing through the Project.json examples I was wondering why the said options are using strings instead of arrays, especially in the Entity Framework project.json example

{
  "code": "**\\*.cs;..\\Shared\\*.cs"
}

This reminds me of %PATH% on Windows or Unix/Linux and I personally find it really hard to read it. Also it introduce an additional step for me to split that string to get all paths.

So my proposal here would be to use a simple array, which should be not only easier to read but also easier to parse.

{
  "code": [
    "**\\*.cs",
    "..\\Shared\\*.cs"
  ]
}

This should also apply to other options such as exclude, resource and shared as I assume that they allow us to specify multiple values if required.

{
  "code": [
    "**\\*.cs",
    "..\\Shared\\*.cs"
  ],
  "exclude": [
    "buggy/**/*.cs"
  ],
  "resources": [
    "embed/**/*.*"
  ]
}

Oh, I haven't seen that. Sorry about that.
Good that there's already an issue about that :)
