- redid autoload handler and resource file filtering to use the newly defined method with multi-part names.

As a result the old 'Group' property could be removed and all other means to get a section name were disabled.
As an example, if the code gets 'doom.doom2.commercial' it will use the following sections in this order:

global.autoload
doom.autoload
doom.doom2.autoload
doom.doom2.commercial.autoload.
