Dead links in Minuit2 documentation

On this page, the link to testMinimize.cxx is dead. Could you fix it? The same for the link to https://root.cern.ch/doc/Minuit2.tar.gz.

In addition, I think there is an extra “*/” at the bottom of this page.

I have updated the corresponding page(s). I let @moneta confirm the changes I did are correct. At least they are not dead links now. The doc will be updated tonight. Thanks to have seen these defects.
