[svn-r2007] Datasets.html

Groups.html
	Added note that object names (in Groups.html) or dataset
	    names (in Datasets.html) must be unique.
	Changed 'boot block' to 'super block'.  (Groups.html only)
Files.html
	Minor formatting fixes.
Datatypes.html
	H5Tconvert:  Added plist_id parameter.
References.html
	Deleted "not implemented" and related messages.
	Added description of H5Rget_object_type.
	Deleted all material about internal dataset region references.
	    [Unlikely to be implemented (QK) and there was very little info.]
	Commented out references to H5R_BADTYPE.  [This appeared in the
	    list of "valid types", which it is not.  And user is instructed
	    to test for 'a negative value' rather than 'H5R_BADTYPE'.
	    So this was deemed not to be user-level information.]
	Changed 'boot block' to 'super block'.
	Other minor editing changes.
