Merged oop changes to plugin loading into trunk. Also removed some missing paths from the project file and set laz to build in a build/$(TargetOS) folder instead of building where the sorces are... its cleaner imo. In the IOManager branch I coded for passing the plugin path down to the mufasa library so it can load components (e.g. eios and a system i'm planning for multiple script components). I'll probably be quite for a while as I work on SMART.
