This is a patch to add a custom header to .properties files and match the
features of the ExtendedProperties class in [collections] so that it can be
deprecated. I preferred using a get/setHeader instead of a header parameter on
the save method, this will spare the hassle of carrying the header every time
the configuration has to be saved.
