Secured Object for Database Abstraction

Release Notes: This release adds the ability to change the type of database on the fly by setting the property _dbtype. It adds methods to lock and unlock the object used to export it in a more secure way, by verifying when importing it whether the file base.inc.php is the same as its creator. There is better error management.

Release Notes: Bugs from the 1.RC3.2 release were fixed. The code comments were translated into English. This version is stable for production use.

No changes have been submitted for this release.

Release Notes: A bug in the object request of the previous version that was inserted for testing purposes was removed.

Release Notes: The parameters for the creation of the object were reversed. The type of the driver is given as the first parameter. This is better for drivers like sqlite or firebird which open a file and don't need a password or user name. The documentation was also changed.
