Dump_lightmaps Fix (map2dif)

Not sure if this is really or bug or not but here is a quick fix to get it going..

lmpacker.cpp

//~ line 14 add
#ifdef DUMP_LIGHTMAPS
#include "core/fileStream.h"

#endif

//~ line 296 add
#ifdef DUMP_LIGHTMAPS
    static U32 majCnt = 0;
    U32 minCnt = 0;
	
    FileStream output;

	dPrintf("\nexporting lightmaps...");
	output.open(avar("lightmap_%d_%d.png", majCnt, minCnt++), FileStream::Write);
    m_sheets[0].pData->writePNG(output); 
	dPrintf("finished\n");

    majCnt++;
#endif

map2dif will now dump the lightmaps and the lightmap normalmaps after each sheet is assembled

edit : oh compile with the DUMP_LIGHTMAPS preproc define /D "DUMP_LIGHTMAPS"
