aafe169f89
Added adm/qmake/Occt.pro for building OCCT using Qt Creator. genproj/genconf scripts have been extended with an option defining project format. Draw_Appli now tries resolving CASROOT/DRAWDEFAULT/CSF_OCCTResourcePath/CSF_OCCTSamplesPath locations within usual OCCT development/installation environment. Added missing TKShHealing dependency to TKDraw/DRAWEXE (inherited from TKMesh). OSD_Process::ExecutableFolder() - added method returning executable folder.
