Custom Container Pack for Delphi XE2 to XE7

I just updated the Custom Container Pack sources to support Delphi XE2 to XE7. It was mostly a matter of creating the packages for the newer versions. I also had to adapt the registration code to changes in Delphi XE2.

It now compiles and installs. I have not tested it extensively. We use it at work with Delphi 2007 and I know of no bugs with it.
