Test Project Created

+ Implemented Request Processing (Cache => Regex Events => Razor Pages => Static Content)
 + Rendering based on domain works
 - Areas are not implemented
 + Content Type Map now defines `.cshtml` files and default mime type was changed to "text/plain"
 + GetStaticFile no longer returns private templates/layouts (used to be able to view those in plain text by requesting with a fully qualified path)
I will make more concise tests in a bit (I was not pushing to git properly, so have to make big commits for the time being)
