Revert "Merge pull request #733 from sonatype/activate-first-restlet1x-plugin"

This reverts commit 49c2512c2aa57160a3caeabc496e4dbf7c2840cf, reversing
changes made to 88b62c95a897ca10c38688eb58d55994df18fccd.
Fix the filter pipeline startup issue by giving all components in the restlet1x plugin the same low-level ranking as Nexus core, ie. zero.

These components will then be ordered in sequences after components from other plugins, which makes sure that the restlet1x 'catch-all' filter will not kick in before other filters in the dynamic pipeline. Normally each plugin is assigned a higher-level ranking based on their activation order, ie. the same as Plexus, to allow plugins to override selected components from core or dependent plugins. Without this change if the restlet1x plugin started after the siesta plugin then the 'catch-all' filter would get a higher ranking than the siesta filters, and the siesta filters would never be called.

Note that default components will still appear before non-default components, regardless of which plugin contributed them. The ranking function effectively partitions components into default vs non-default where elements in each partition are sorted by their assigned ranking (and then by their defined order inside the injector).
