Recommendation Tracker Code

CommentRefsTablePanel:
== Deleting a comment removes the reference from the Group/Recommendation and then marks the Comment element as "deleted".

SynchronizeClient:
== Now deletes elements if they are NOT referenced and sets the correct SyncResponseCode. It had been executing isReferenced(...) and only deleting if it returned true.

CommentTypeDAO:
== Now looks at both the application_id and the comment_id when checking references. It had been just looking at comment_id's which are not unique amongst Applications.

CommentHelper:
== Correctly checks if a comment is referenced from a Recommendation or a Group.

UpdateTransactionManager:
-- Removed a bunch of unused code.

Updates to Sync process. Now commits and syncs changes. I haven't worked out all test cases and I am sure that complex sync cases will break everything. I still need to handle errors in a better way and deal with initialization errors within my SynchronizeTransactionManager and UpdateTransactionManager classes.

ResultSet.getDate(...) returns only MM:DD:YY information and not HH:SS. Because of this it itmes which are "NEW" might not be correctly identified. ResultSet.getTimestamp(...) was used instead which returns java.sql.Timestamp (which extends Date) to preserve date AND time information. The change is transparent to other sections of the code.

removed old unneeded property
