WOK scripts used in generation of MSVC projects are put to adm/genproj.tcl
Batch script genproj.bat added, replacing 'wgenproj' command of WOK.
WOK tool for configuring custom.bat is also copied; it is called by genproj if custom.bat does not exist
Environment variable SHORTCUT_HEADERS can be defined in custom.bat to have headers put in inc just shortcuts to actual headers, instead of copies.
Corresponding option "copy OCCT short-cut headers instead of original one to inc folder" is added to genconf dialog
