Add the ability to update remote database with local modifications

[shulard]

Sometimes during evolution development, the database is updated with new fields, new values that must be populated in the remote one.

We need to have a script which can synchronize :

• Schema updates
• Options values updates
• Maybe content

Maybe the DbDeployTask in Phing can be useful for that : http://www.phing.info/docs/guide/stable/DbDeployTask.html

It allow to build update script / undo update script from delta SQL... But it does not allow to generate delta SQL.
