Sample unassembled monodoc files

Description of Problem: monodoc crashes when viewing/editing custom docfiles
via the --edit commandline parameter.

Steps to reproduce the problem:
1. monodocer -assembly:path-to-the-DLL -path:docfiles
2. monodoc --edit docfiles
3. Click on one of the childnodes for your documentation


Actual Results:

ArgumentNullException and/or displays the member name instead of the
documentation like..  

M:Namespace.Something.Somethingelse

Console Output is as follows:

Loading uncompiled help from docs

  Note: Applications can use GLib.ExceptionManager.UnhandledException to handle
the exception.
System.Reflection.TargetInvocationException: Exception has been thrown by the
target of an invocation. ---> System.ArgumentNullException: Argument cannot be
null.
