[ci skip]
no issue
- update grunt-jscs dependency
- fix deprecated `validateJSDoc` configuration
- fix numerous linting errors, including:
- use of future-reserved `public` and `private` variable names
- use of `[]` instead of dot-notation (especially `express['static']` and `cacheRules['x']`)
- extra spaces in `const { run } = Ember` style constructs
One issue that did become apparent is that there are conflicting rules that prevent the use of object function shorthand such that both of these:
```
{ myFunc() {} }
{ myFunc () {} }
```
are called out due to either the missing or the extra space before the `(`
