1. Made it possible to upgrade from acs-kernel 4.6.1 to acs-kernel 4.6.2
by using the APM rather than running the upgrade script by hand from
PSQL or SQL*Plus.
2. Changed a bunch of package .info files to depend on acs-kernel 4.6.2
to force the APM to upgrade acs-kernel (and therefore the APM datamodel)
before anything else. No guarantee on this though since not all
packages properly define their dependence on the kernel, it appears.
3. Whacked the release notes to suggest people use the APM to upgrade
acs-kernel first, other package later, just for safety's sake.
4. Fixed goof-up in acs-subsite I accidently introduced.
