#288: Create prototype for legacy database schema proxy

 As discussed on the dev mailing list and documented in
 schema-changes], we want to make product a first class citizen in
 Bloodhound. This would be (as proposed) be implemented by introducing new
 column (product) to tables that hold per-product resources (milestones,
 components, versions,...). As this would break existing trac/plugin
 compatibility, the idea is to produce a database proxy component
 (prototype for starters) that would 'install' itself directly above the
 database, parse the SQL statements and modify them in such a way that
 would limit the scope (of the SQL statements) to the product in current
 scope. Using this approach (if it turns out to be feasible at all) we
 would keep compatibility with both trac and plugins and still be able to
 change the database schema as proposed and at the same time allow
 multiproduct aware code/plugins to leverage the new database schema.
