Updates ASP.NET package versions to 2.1
Tweaks TFMs
- libraries = netstandard2.0
- exes/apps/tools = netcoreapp2.1
- unit tests = netcoreapp2.0
- e2e tests = netcoreapp2.1 (dependency on apps)
The exception to this is the Browser.JS project which depends on our
tool for its build. however this project just builds the js code so its
TFM doesn't really matter.
Adds conditional attributes for HTML elements.
This means that an attribute with a 'false' .NET bool value or a null
.NET value of another type will not be rendered in the HTML.
