A new Slash::DB can't be created someplace where it will go out of scope

before the installation process is complete.  Since we're using
connect_cached, the Slash::DB object actually gets the same DBH as the
Slash::Install object itself, and when it goes out of scope both DBHs
get disconnected.  So, it's now an instance variable that persists for
the life of the Slash::Install object.
