Support mutiple database instances

[Герхард PICCORO Lenz McKAY]

after a hard comparison between the two profiler addon for codeigniter, forensics are the better by so far! forensics handle and show many more date rether thatn others "complex addons"

if i have multi db instances in controller profiler forensics does not handle any db output, code example:

class Welcome extends CI_Controller
{
    public function index()
    {
        $this->DB1 = $this->load->database('development', TRUE);
        $this->DB2 = $this->load->database('development2', TRUE);

        $this->DB1->select('*');
        $result1 = $this->DB1->result();

        $this->DB2->select('*');
        $result2 = $this->DB2->result();
    }
}

there's some way to handle multi DB instances and show the querys, i try some patches backported from CI 3 brand but no success!

the commit e771df4 will solve that!
