Currently, CodeRush provides the capability to store team settings and images used in Rich Comments and they should be shared among all team members. I have corrected the gitignore file to exclude only personal settings.

Ignoring `launchSettings.json` does not make much sense. Now .NET CLI even considers this file when running with `dotnet run`, as you can read [here](https://docs.microsoft.com/en-us/dotnet/core/tools/dotnet-run?tabs=netcore2x).

This settings will be useful if shared among project members, so it should be commited to the repo.

Also, on the default `.gitignore` file generated by Visual Studio it is not ignored, so this causes confusion, as depending on how `.gitignore` was created it could be commited in or not.

The conversion process from the old custom rptproj to the MSBuild based projects creates a .bak backup file

The VS 2017 version of the Business Intelligence project contains a user file (*.rptproj.rptuser) that should be ignored as well

* Add *.snk strong name key files

Strong name key files shouldn't be included in a repository AFAIK. they are intended to sign build output to verify that it comes from the correct publisher. having an *.snk in a repository would allow anyone to produce build as if they were the original publisher.

I guess some OSS projects might like to have *.snk files in their repos but that would be an exception to the rule.

* Make use of *.snk optional

Add note explaining use.

* Reduce explanation

Just use a link instead

* Update VisualStudio.gitignore

It looks like VS2017 changed it's nuget package directory name to be capitalized.
When using Ubuntu for Windows, directory name casing of NuGet package folder becomes important and detected as a change by git,. This change is to ignore regardless of casing.
