- npm run lint was run twice in CI

- linting does not need to be run on AppVeyor, there was a weird bug on Windows Node 4 + ESLint

Requires a spaces after an if and before the opening brace of blocks

Adds $regexp operator for MySQL and Postgres and its negated and case-insensitive versions.

* Hint for async

I added a hint for the await keyword wich has increasing support. But maybe useless because everyone should know this possibility for promises.

* Added async docu link

Added furthermore that await only works in async functions.

… queries for sqlite (Closes #7759)

* update changelog

* add test

* add class method "increment"

Basically moving code from instance method `increment` to class method `increment`.

close #6359

* fix tests. change: require options.where

Column comments are not a currently supported feature and should not possess documentation references.

Documentation should be readded when the feature is supported once again; until then, the documentation is inaccurate and misleading to users.

```
User.findAll({
    where: {
        '$Instruments.name$': { $iLike: '%ooth%' }
    }
    include: [{
        model: Tool,
        as: 'Instruments'
    }]
})
```

Did not have a comma between the key `include` and the key `where`. People who would copy/paste this code would get an error.

A comma was added.

Finding content within the doc is a pain, so adding a link to their sections in the markdown should help. Also styled the class methods in the headings on the page.

* Update models-usage.md
