Profile class getDetails

[Isigar]

Profile class is nice but i need to get all the data or just get some quickly.
So i added one new method getDetail only.

Usage:

$this->getDetail(["name","birthday","gender","email"]);
- default value is "name"

I have no idea what this is about since I never used this library. What do you think @PavelJurasek?

I haven't used this class in my projects either.

Looking at the commit, I wouldn't really change the implementation of getDetails method as it would introduce a BC break.
Calling new method getDetail with different values wouldn't work either. The idea might be good, but the implementation is lacking robustness.. Not to mention the violation of coding style.
