Core: Update CModelLoader

Updated CModelLoader to work with new HDF parser.
Common: move Vector comparison operators

Operators ==, <=,>=, <, >, != are just confusing, because there are many
ways of comparing two vectors (e.g. length, coordinates, direction), so it
would be unclear what is being compared.
Filesystem: Update CFileSystem

Remove CHndfParser.h include.
