Add `-overrides' to the monodocer command line. :-)

-overrides will add members which are overridden into the XML file; for
example, System.Windows.Forms/en/System.Windows.Forms/Button.xml would

    <Member MemberName="OnMouseLeave">
      <MemberSignature Language="C#" Value="protected override void
OnMouseLeave (System.EventArgs e);" />
        <Parameter Name="e" Type="System.EventArgs" />
        <param name="e">To be added.</param>
        <summary>To be added.</summary>
        <remarks>To be added.</remarks>
        <since version=".NET 2.0" />

Note (1) the <MemberSignature/> includes `override', and (2) there is a
<since/> element noting that this member was added in .NET 2.0.

The only thing missing is that <summary/> and <remarks/> should have
pre-canned text:

	This member overrides <see 
	  cref="T:System.Windows.Forms.ButtonBase.OnMouseEnter" />

and it should be fairly easy to implement that support.

Does this suffice?

The only remaining problem is that monodocer occasionally hangs when
processing an assembly.  I'm still looking into this (and wondering how
many chickens I need to sacrifice in order for mdb to actually work).
