Moved all dependency information to a new page, Appendix C.
Appendix C also contains information concerning the build order.
While there might need to be a few tweaks yet, this information is complete
enough at this point to close out the long-standing ticket #684.
Many thanks to Chris Staub, Dan Nicholson and Manuel Canales Esparcia for
helping get this finished.
