Make tslint.json to be simple with extends standard.

[huan]

To make tslint.json be simplify:

{
  "extends": [
    "tslint:recommended",
    "tslint-config-standard"
  ]
}

If we use the above setting for tslint, the current project has many warnings.

We need to:

1. change tslint.json to the above setting
2. add custom rules to tslint.json to satisfy npm run lint with the current project code base
3. look into the new tslint.json, study it and then to select: which rule need to follow by changing the code style, and which rule we need to keep customized.

Done.
