function view::start_query_capture

Set up query capturing.

Db_query() stores the queries that it runs in global $queries, bit only if dev_query is set to true. In this case, we want to temporarily override that setting if it's not and we can do that without forcing a db rewrite by just manipulating $conf. This is kind of evil but it works.

public function start_query_capture() {
    global $conf, $queries;
    if (empty($conf['dev_query'])) {
        $this->fix_dev_query = TRUE;
        $conf['dev_query'] = TRUE;
    }
    // Record the last query key used; anything already run isn't a query that
    // we are interested in.
    $this->last_query_key = NULL;
    if (!empty($queries)) {
        $keys = array_keys($queries);
        $this->last_query_key = array_pop($keys);
    }
