Classified Ads merged back to, patches upcoming

The classified fork of module Classified Ads, originally maintained here, is now back to as branch 6.x-3.x of the module.

All 5.x features requests have been updated to 6.x-3.x, and bug triaging will be coming next, to check what is still relevant these days and what was just needed because of 5.x limitations.

The goal is to have a clean-again issue queue by mid-August 2011n, possibly with some new features.
