- Changed some symbols to be platform-independent
- Now the CGraph_Retail::copyOverTo method doesn't automatically fall back to manual copy (instead of memcpy) on GRAPH_VERSION increments
- Added dlls/nodes_compat.h, which implements two stub classes for reading legacy CGraph and CLink
- Modified CGraph::FLoadGraph in dlls/nodes.cpp to take advantage of them if GRAPH_VERSION != 16 == iVersion
- Slight changes to dlls/nodes.h to be able to test for the value of GRAPH_VERSION in preprocessor directives
