api.css not included

[matjack1]

Hi @cebe,
following your commit 13ba053 I was checking how it was rendered now, but it looks like the file api.css is not included in the building process (https://github.com/yiisoft/yii2-apidoc/blob/master/templates/bootstrap/assets/AssetBundle.php#L22).

Is that deliberate? If so, would be better to move the CSS rule in style.css?

If I understand the rationale I'm more than happy to help out a bit with some code :)

sounds like a bug, either both css files should be included or they should be merged. Merging sounds more reasonable to me. You can work on that if you want.
