Adds .Rprofile and r.org to the project.

r.org will become a template file of sorts for the various IPSUR
chapters. It is copied from my Analytic Templates project.

.Rprofile is also from my Analytic Templates project, and it is
basically just like all my other .Rprofile files.
Adds IPSUR to the list of packages to make sure are installed upon startup.
