ADD googlescholar command

[MonoHue]

I added Google Scholar info to basic info, it may help researchers present themselves. I also add an example to resume.tex.

In result, it looked like this below:

This is a good idea! But I would prefer a general implementation where each user can choose an icon for a new item themselves.

The current implementation, which only adds a Google Scholar icon, is too specific. For now, let's keep this open, and you can create a new pull request for a more general version. Alternatively, I might add it in the next release if I have time.

If it turns out that no one creates a general implementation, we can reconsider your approach :)
