Add support for importing index.js from aliased directories path

Fix #37

I have written new tests, and tested it in one of my local projects. Everything works I think, but one may look into tests, because I'm not expert in testing.

Appveyor test returns false, while Travis true. Not sure if my patch destroyed something, but it shouldn't. This may be false negative check, at least for that PR.

Why is this hasn't been merged?

[soanvig]

Repo is inactive for a long time. I could be eager to take ownership if I maintain more projects, that use Rollup. For now I have only one or two such.

You may want to use directly my fork (npm supports external repositories). You may see Google, if you don't know what Im talking about.

Hi @soanvig, thank you for your pull request. I've commented on the corresponding issue (#37) as well.

The idea here is that Rollup plugins have a specific responsibility. For this plugin it's to only provide aliases, but not to enhance the resolution algorithm in any other way.

The recommended approach is to use rollup-plugin-node-resolve which allows to resolve index.js files and use it in conjuction with rollup-plugin-alias. Please feel free to open an issue if that doesn't work you.

If you think this is still unresolved, leave a comment and I'm happy to discuss this further.
