This bumps and locks at 1.60.0 to cope with whatever binding policies .NET Core is enforcing - then we can stick at this until 2.x I guess.

This PR is for the issue I raised earlier #1194 

- I've added links for all every issue
- Tidied up capitalization 

Let me know if you need me to make any changes

In cases where the object has a property named ID, the property will automatically be assigned as [Key], even if [Computed] is added manually in an attempt to override it. This can cause confusion, this exception will be thrown despite the code looking fine and there only being one [ExplicitKey] defined. I've added this extra line of information to help diagnosis.

Fixes #620

Added a section to indicate Dapper works well with User Defined Variables.

Lots of runs is good, but changed behavior and greatly affects stability (due to GC).

Adds Dashing benchmarks to Dapper.Tests.Performance

Added Linq2DB benchmarks

This is prepping a run we can drop into the README easily. And more info on allocations and such along with it. It's finishing off the benchmark port getting it into a good output state (something we can copy/paste). It removes Simple.Data because the package was debug and causes a lot of issues.

This doesn't output 100% like we want yet (fastest to slowest). BenchmarkDotNet joins summary results after ordering...we need to post-order that. I'm asking the maintainers how to do so.

Also note Belgrade was not parameterizing before, giving it a huge unfair advantage. This has been fixed to be apples:apples.

MySql.Data is a travesty at this point - moving to something more stable. Really we weren't testing Dapper with previous test failures, we were testing what mood MySql.Data and NuGet extraction are in and which phase of the moon is about.

Also speeds up the builds with 1 restore and 1 build. We can simplify here because everything is relevant (no wasted builds).

- Moves to NerdBank git-based versioning
- Cleans up build.ps1 to current (will tweak for older moves later)
- Updates xUnit to latest
- Moves to dotnet test, since they killed dotnet xunit
- Testing SQL Server CE has become unreasonable. It's gone (minimal cleanup in this commit disabling it).

instead of exception message of `DateTime`, you'll get `The type 'DateTime' is not supported for SQL literals.`, which is much more helpful when trying to figure out what went wrong

Fixed incorrect indentation in Readme.md

System.ArgumentException is thrown when passing empty SqlDataRecord list as an anonymous object or as table-valued parameter to Dapper. Added two unit tests.

Use adapter to format column name equals, bringing it in line with `Delete` behaviour.

Made the same fix to `InsertAsync`

#418 - `Update` was fixed but `UpdateAsync` was not fixed.

The -Contains operator doesn't do substring comparisons.

> -Contains
>Description: Containment operator. Tells whether a collection of reference values includes a single test value.

Should be using -Match operator instead.
