Initial checkin
Changed "Add" to "Add..." because dialog will follow
Added "Add Files" dialog + fixed "Add to .cvsignore" bug
Added "Add Files" dialog
Popup menu checks selected file type
Added "AddFiles.cpp / .h"
Fixed handling for filenames starting with a dash. But CVS itself is buggy here too, so it doesn't always work anyway :(
Fixed bug "cannot add .exe files"
