Making apm_source update the apm_library_mtime variable (just like the analogous proc for xql files does). Making installation log much less information to the browser (changing from apm_ns_write_callback to apm_dummy_callback). Moving initialization of util_memoize cache to happen before first package is installed (fixes bug 242).
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.
