[svn-r152] Changes since 19980107

----------------------

./html/Datatypes.html
	Updated to match code.

./src/H5Odtype.c
./src/H5Oprivate.h
./src/H5Tpkg.h
./src/H5detect.c
	Changed H5T_FIXED to H5T_INTEGER.

./src/H5T.c
./src/H5Tprivate.h
./src/H5Tpublic.h
./test/dtypes.c
	Implemented lots of type properties.

./src/H5detect.c
./src/H5Tpublic.h
	It is no longer necessary to call H5init() before using a
	predefined data type.
