Once again, multiple plugin directories feature.

Hi, I'm starting over a new project, and I now feel the need of a separate plugin directory for a specific project. I don't like having one copy of Smarty per project, nor one copy of plugins per project. I remember that someone suggested once that we could have 2 plugin directories, the main one, and one that can be setup for a specific application (by instance). This way, you can develop particular plugins for a specific project, or even override the core plugins in that second directory, since it was suggested that the search order for plugin files would be 2nd directory then main directory. It would also help when upgrading Smarty, since you can be 100% sure that the files in smarty/plugins are the original ones. Any thougts ? Bertrand
