Untabification of readme.txt

[atifaziz]

Helps avoid warnings of mixed tabs and spaces in VS editor like:

This happens when someone copies the following text from readme.txt into their AssemblyInfo.cs:

[assembly: AssemblyVersion (ThisAssembly.Git.SemVer.Major + "." + ThisAssembly.Git.SemVer.Minor + "." + ThisAssembly.Git.SemVer.Patch)]
[assembly: AssemblyInformationalVersion (
    ThisAssembly.Git.SemVer.Major + "." +
    ThisAssembly.Git.SemVer.Minor + "." +
    ThisAssembly.Git.SemVer.Patch + "-" +
    ThisAssembly.Git.Branch + "+" +
    ThisAssembly.Git.Commit)]

Being tabs the default in VS for C#, I think we just need to pick one and live with the fact that some will see that warning.

Thoughts?

I felt that tabs may have crept in accidentally so thought I'd help out with a PR. However, if they are intentional then I can live with the warning and fix on my end each time. It's not a lot of work at all so no need to go down a tab vs. spaces rabbit-hole (that always runs deep). I'll leave the decision to you. You can merge or you can just close with the peace of mind that I will be neither offended not disheartened. 😄

Fair enough. I'll leave it open so that more users wanting the change (or not ;)) can chime in though.

Thanks!

I think for the readme it's fine to unify on spaces
