DB Layer:

- Make SQL Transactions actual objects used in code. (Thanks to Derex for the idea)
* Uncommitted transactions will be automatically rolled back and cleaned up using ACE_Refcounted_Auto_Ptr, so no need to call Rollback() in the code.
* Prevents recursive transactions and makes developers aware of transactions going on.
* Gets rid of unneccesary overhead iterating over a concurrent map.
- Some cleanups in affected code, including better usage of transaction control in AH / mail related code to prevent data loss.

*** Experimental, use at own risk, recommended to backup your DBs. ***
