Special characters not escaped correctly

Using special characters in non-code md breaks html rendering.

Example: https://api.armory3d.org/iron/Scene.html#getChildren
… html after `@return` is cluttered as it's defined as:

```haxe
@return Array
```

This works:
```haxe
@return `Array`
```

If this is intentional and not gonna get fixed it should be noted in the documentation.
