Portals form; Test page; "Test Compile" now reports the file sizes in bytes of the generated .NET Assemblies

Every time a Portal is compiled, it generates multiple .NET Assemblies; one for the Master Page and one for each individual page.

The "Test Compile" button on the Test page of the Portals form will now report the size in bytes of the generated Assemblies.

NOTE: This size is purely the number of bytes output by the Roslyn compiler.
