Dirk and I updated REP 122 to reflect the current design of the
install tree and of catkin.

The previous REP 122 version was still in "Draft" status, so I updated
that, adding a "Fuerte Differences" section to document how that
differed from the current (Groovy Galapagos) specification.

The latest version can be viewed conveniently from github account
using the built-in .rst formatting:
