Recommended changes resulting from automated audit

[Jericho]

We performed an automated audit of your Cake addin and found that it does not follow all the best practices.

We encourage you to make the following modifications:

• [x] You are currently referencing Cake.Core 0.26.0. Please upgrade to 0.28.0
• [x] You are currently referencing Cake.Common 0.26.0. Please upgrade to 0.28.0
• [x] The Cake.Core reference should be private. Specifically, your addin's .csproj should have a line similar to this: <PackageReference Include="Cake.Core" Version="0.28.0" PrivateAssets="All" />
• [x] The Cake.Common reference should be private. Specifically, your addin's .csproj should have a line similar to this: <PackageReference Include="Cake.Common" Version="0.28.0" PrivateAssets="All" />
• [x] The nuget package for your addin should use the cake-contrib icon. Specifically, your addin's .csproj should have a line like this: <PackageIconUrl>https://cdn.rawgit.com/cake-contrib/graphics/a5cf0f881c390650144b2243ae551d5b9f836196/png/cake-contrib-medium.png</PackageIconUrl>.

Apologies if this is already being worked on, or if there are existing open issues, this issue was created based on what is currently published for this package on NuGet.org and in the project on github.

@Jericho Thanks for the heads up. Am I correct in assuming these are the best-practices you are talking about?

[Jericho]

Yes it is. Although, to be honest with you, I don't think the page is fully up to date. For instance, it's still talks about 0.22.0 being the most recent version of Cake and it also talks about IL merging your dependencies which is no longer necessary.
