Update default-config to check for FvwmPrompt.

  Currently the default-config assumes FvwmConsole exists. This
  makes the default-config check for FvwmConsole and FvwmPrompt
  and add correct menu entries for the tool that is found.

  This also adds FvwmMFL to the list of modules started by default
  so FvwmCommand and FvwmPrompt work without modification in the
  default-config.
