* monodocer.cs: FieldInfo.GetValue() may throw, particularly if getting 
          the value of a public+static+readonly field, and the constructor for 
          the type of said field throws an exception (though DocTest-v1.cs has
          a similar scenario).  This is bad, as it prevents monodocer from
          completing its work.  Found by Dan Morgan.
        * DocTest-v1.cs: Create a `public static readonly` field that will
          generate an exception from the class constructor.
