(GH-356) Remove file header

[Witteborn]

Description

I searched for the file header (ctrl + f: "// ---") and removed every one I found.

Related Issue

Resolves #356
This is also part of the issue #261

Motivation and Context

As mentioned in #261

Classes in the GitVersion project don't contain any file header. A class rename don't change the filename in the header, which cause a warning and increases the maintenance effort.

How Has This Been Tested?

I did not change any actual code.

Checklist:

• My code follows the code style of this project.
• My change requires a change to the documentation.
• I have updated the documentation accordingly.
• I have read the CONTRIBUTING document.
• I have added tests to cover my changes.
• All new and existing tests passed.

I could not pass the integration tests and I'm not sure why.
They didn't pass before and after the change.

@Witteborn thank you very much for taking the time to update this. I agree that the current copyright header makes refactoring the code difficult. At some point, we may add back in an alternative copyright header, but for now, removing what is currently in place, makes a lot of sense.
