[Catalyst] default template

[Octavian Rasnita]

Ok, thank you for this code.

I haven't seen very many explanations about RenderView, so I didn't 
understand how it works.

So I have used only RenderView until now, but not very smart, something 
like:

sub end : ActionClass('RenderView') {
my ($self, $c) = @_;
$c->forward($c->view('TT'));
}

So it was just like a common sub : Private action.
