Automatically save init file when a resource is modified

previously, init was autosaved only when a resource was modified using the menu. I have also
included modifications through lua code.

To avoid wasting resources, the file is not saved immediately, but with a 5 second delay (to
enable saving a bunch of changes in one go)
