Create a component detector for C# (~60 new lines of code)

[prokopsimek]

We'd like to measure the quality of apps written in C#.

There are "component detectors" to determine frameworks, platform, and type of an application.

It's necessary to implement CSharpComponentDetector the similar way as is JavaComponentDetector implemented. Because C# is not a front-end language, so it's not necessary to recognize Frontend/Backend platform.
It's around 60 new lines of code including tests.
