Remove nuget targets from all projects

I removed all nuget targets from the projects. I deleted all the .nuget directories. Then removed tags from csproj files. While I was doing this VisualStudio formatted the project file but actually I deleted the following tags:

<SolutionDir Condition="$(SolutionDir) == '' Or $(SolutionDir) == '*Undefined*'">..\</SolutionDir>
<RestorePackages>true</RestorePackages>

<Import Project="$(SolutionDir)\.nuget\nuget.targets" />

If you do not want to remove the nuget targets just reject this pull request.

Have a nice day
