Added osg::MemoryManger which is currently based on Paul Nettle's memory manager published at flipcode. I havn't adopted Paul's macro's for new/delete etc, but use osg prefixed versions instead to allow greater flexiblity in handling include ordering. Have fixed a couple of new/delete[] problems which existed as a result. To use the MemoryManager to track memory usage simply add -DOSG_USE_MEMEORY_TRACKING to the compile line. Have yet to move the osg from using new to osgNew, will do this next.

#include <osg/Export>
Added support for osg::MemoryManager which is based upon Paul Nettle's memory manager published at flipcode.com. This can be turned on with the OSG_USE_MEMORY_MANGER option which then uses custom global new and delete operators as well as provide osgNew and osgDelete macro's which add ability to log line and file from which calls are made. Updated osg,osgUtil,osgDB,osgText and osgPlugins/osg to use osgNew/osgDelete, and fixed memory leaks highlighted by the new memory manager.
