moving the mounting of core packages from the bootstrapper to the installer. To enable this I am setting up a more complete Tcl environment before installation of those packages by sourcing procs in acs-subsite and certain init files in acs-tcl as well as redefining ad_conn. This also means that core packages have a more complete environment when/if they use post-instantiation procs.
moving instantiation and mounting of all core packages (acs-lang, acs-admin, api-doc etc.) except acs-kernel and main site (retained because they are needed during install) from the acs-install.sql file to the Tcl proc apm_mount_core_packages that is invoked on first startup. Note that this unfortunately means that callbacks will not be invoked for the main site node and for the acs-kernel instance.
