Fix missing doomgeneric

Fix missing doomgeneric

Fixed. Instead of a submodule, CMake will just fetch the github repo in it's configuration in Qt Creator.

@devmchechi Added ESC handling. If you press esc for 1 second, it returns to the nav home. If it is less than a second, it toggles the menu. This function exists everywhere in the doom game because the doom menu state isn't exposed to the QML. The esc button press time can be modified to be longer if needed.
