* CMeshManager: Changed to check for .pmd and .dae files and convert and cache as appropriate. * CModelDef: Fixed misinterpreted doc comments in. * lib: * Fixed init/shutdown sequences to support multiple VFS-using tests correctly. * Fixed most reported memory leaks from the new leak-reporting test system. * Fixed error when trying to dump debug data about fonts after unloading them. * Added sphere dae/pmd data for tests. * Added output buffering to DAE->PMD converter. * Added precompiled COLLADA converter DLLs. * Removed old redundant conversion script. This was SVN commit r4709.
