minor readme fixes
We don't need a type check because shouldly constrains by using generics which fixes another failing enumerable scenario
Converted Should[Not]BeEmpty for collection tests
Fixed some broken tests
Converted ShouldBeSubsetOf
ShouldBeInRange tests converted
Moving a few test classes and helpers into folders to group better
Moved more files
Converted should not be one of tests
Moved the scenario base classes into test helper folder
And a few more of the test types into test helpers
Should[Not]BeSameAs tests converted
Migrated Should.[Not]Throw tests across to scenarios
Added more Should.[Not]Throw tests, especially around tasks
Removed some duplicate tests and migrated last few missing tests
Fixed build
change out .Count() to .Any(), tidies up code slightly (I think), plus could have positive perf impact on large IEnumerables
