A new rendering pipeline

🌐 There's a new option in Composite.config that allows rendering pages without using ASP.NET Web Forms internally.
```
<configuration>
  <Composite.Core.Configuration.Plugins.GlobalSettingsProviderConfiguration ..>
    <GlobalSettingsProviderPlugins>
      <add ... omitAspNetWebFormsSupport="false" />
```
🐎 When set to "true", rendering UserControl functions is no longer supported, but in exchange, there's a performance gain and it enables us to build some rendering related features on top of it, namely "donut caching".

"Donut caching"

On a page with dynamic/user specific content, where ASP.NET full-page caching is usually not applicable, now it is possible to mark certain functions as "excluded from the cache". By doing so, you will have all the other parts of the content cached server side.

To use the feature:
➕ Add or set the attribute value omitAspNetWebFormsSupport="true" in /App_Data/Composite/Composite.config
Override PreventFunctionOutputCaching on a Razor function with dynamic content:
```
@inherits RazorFunction

@functions {
    public override string FunctionDescription { get { return "Shows a timestamp"; } }
    public override bool PreventFunctionOutputCaching { get { return true; } }
}

<div xmlns="http://www.w3.org/1999/xhtml" style="color:red; font-size:34px">
    Timestamp: @DateTime.Now.ToString("s")
</div>
```
🌐 1. Enable the full page caching in web.config
