Saving an often used module can result in a complete disconnect from the web server

[nezbite]

When saving a module that is used often, for example Layout or Prelude, most of the time the web server is not active yet and your browser shows the "Can't connect to server" screen and is thus unable to load the page after completing the compiling process. It should display the Is compiling screen for the duration of the process, so that the page can be loaded instantly, when the web server is available again, instead of having to reload a bunch of times.

Also, we should do something to reduce the waiting time.
