Add log-level option to runtime configuration #51

Add the logLevel property to the runtime configuration and modify
the logger creation flow to parse this option second (if applicable)
after the environmental GCLOUD_ERRORS_LOGLEVEL level variable
and to use a singular instance of the logger class upon library
init. Add corresponding tests and update documentation accordingly.
Add a script to `package.json` for easy coverage without coveralls:
`npm run-script coverage`.

**Original config object:**

```JS
var errors = require('@google/cloud-errors').start({
  projectId: 'my-project-id',
  key: 'my-api-key',
  reportUncaughtExceptions: false, // defaults to true.
  serviceContext: {
    service: 'my-service',
    version: 'my-service-version'
  }
});
```

**Updated configuration object:**
*Notice the `logLevel` property*

```JS
var errors = require('@google/cloud-errors').start({
  projectId: 'my-project-id',
  key: 'my-api-key',
  reportUncaughtExceptions: false, // defaults to true.
  logLevel: 0, // defaults to logging warnings
  serviceContext: {
    service: 'my-service',
    version: 'my-service-version'
  }
});
```
