requireDescriptionCompleteSentence: dot in abbreviation is treated like a sentence end

With this line in config:

```
requireDescriptionCompleteSentence: true
```

dots in abbreviations (like `e.g.` or `i.e.`) are mistakenly treated like sentence end.
For example, this line throws an error demanding `e.g.` to be `e.G.`:

``` js
/**
 * Checks if token is part of an @-word (e.g. `@import`, `@include`).
 */
```

Maybe "sentence end" should be "dot + space" instead of just "dot"?
