Original commit message from CVS:
Documentation updates. All standard library objects and standard
elements are documented. Modified some of the elements to more
accuratly report about their arguments so the documentation builds
more reasonable output.

<!-- ##### SECTION Title ##### -->
GstObject
<!-- ##### SECTION Short_Description ##### -->
Basis for the GST object hierarchy.
<!-- ##### SECTION Long_Description ##### -->
<para>
GstObject provides a root for the object hierarchy tree filed in by the
GST library. It is currently a thin wrapper on top of
<classname>GtkObject</classname>, but eventually will be replaced by a
stripped down version of it. This will remove all the X dependencies from
the GST library, making it much more portably and generally useful.
</para>
<para>
GstObject gives us basic refcounting and parenting functionality, though
it is possible that we could use <classname>GtkObject</classname>'s
equivalent functions. I'll probably use what I have now until I strip
down <classname>GtkObject</classname> to re-parent the hierarchy.
