User defined default template
Please allow users to have default templates and custom usings on loading.
Different users use different nuget packages and namespaces and want to have them declared when launching the website instead of having to add them manually each time anew.
Also allow users to administrate the settings for their default template. IE, allow user to say, by default, fiddles should not be "public". Allow user to say, by default, "auto run" is off. Allow user to save auto-run per fiddle as well.
