     * as part of Moodle 2.0
     * Now I [Sam Hemelryk] hit a conundrum while exploring how to go about this
     * as not only do we want to install the new blocks but we also want to set up
     * default instances of them, and at the same time remove instances of the blocks
     * that were/will-be outmoded by the two new navigation blocks.
     * After talking it through with Tim Hunt {@link http://moodle.org/mod/cvsadmin/view.php?conversationid=3112}
     * we decided that the best way to go about this was to put the bulk of the
     * upgrade operation into core upgrade `here` but to let the plugins block
     * still install the blocks.
     * This leaves one hairy end in that we will create block_instances within the
     * DB before the blocks themselves are created within the DB
