Merge pull request #1328 from bramp/last-mod-rfc-1123

Changed the CHttpCacheFilter to use RFC 1123 complaint dates
Oracle unit tests DDL and DML revisited.
added unit tests for beforeFind() and afterFind() on empty result

when a query does not return results beforeFind() is called for all
eager relations even when main query did not return a result.
This is a behavior change, things are all consistent now.
afterFind() should of course never get called then.
Oracle unit tests: "type" table added.
added UPGRADE note for beforeFind() relational criteria

also fixed UPGRADE file whitespace issues for better readability
