IPMFSSF — URLs need to be corrected

On behalf of Elisa Kendall, Thematix:

A couple of nits – on the cover and in the inventory I noticed you included /PDF/ in the URI for the specification. While in practice that's where the pdf version of the specification might be posted, there might also be a PS version for postscript, etc, and I don't think you want the URI with /PDF/ in it to be the definitive URI for the spec on its cover. Linda would likely catch this in document production, but it's one of the first things I'd fix in FTF. Similarly in the inventory, URLs for the specification don't look right to me, for example, I would think that "http://www.omg.org/spec/IPMSS/PDF/IPMSS1.0.pdf" should be something closer to "http://www.omg.org/spec/IPMSS/1.0/IPMSS.pdf", and similarly with the changebarred version.

Adopt Elisa's suggestions to remove '/PDF' from URIs, confirm document numbers/URIs w/ Juergen prior to submission.
