Reorganising code

System of the subprojects was restructured. Now, "Code" contains only code of Nest-o-Patch itself. HEKAPackages are grouped with ReadPulse and ReadPMaster, since this package is needed essentially only to read HEKA files and is not directly used by Nest-o-Patch. NVUtils were moved to NVComponents, where all my "general purpose" units are now collected.
