Move from obsolete TSD/Typings to Installing using npm

[Ghislain Hachey]

See https://github.com/Definitelytyped/tsd and https://github.com/typings/typings (both deprecated)

This will mean removing tsd and the tsconfig.json file and re-installing all typings like this:

npm install --save @types/lodash

[Brian Lewis]

Note that we now have a first step in this direction as of pull request #304 which installs lodash.d.ts using npm, and references it using the tsconfig.json types compilerOption

  "compilerOptions": {
    "target": "es5",
    "noImplicitAny": false,
    "sourceMap": true,
    "sourceRoot": "../../../Pineapples.Client/src",
    "removeComments": false,
    "allowJs": true,
    "outFile": "../dist/scripts/app/pineapples.js",
    "types": [
        "lodash"
    ]

We can start to migrate others as required - note we have to be careful where some .d.ts files have been edited by hand.
