Option to selectively display "Activate Now" and "Install Now" notices

[Raruto]

This change allows devs more freedom to control which and when to display these admin notices.

If not specified, this is the default behavior (i.e. the same as it already works):

$dependency['activate_notice'] = true;
$dependency['install_notice']  = true;

I have to think about this one a bit. As I see it the only thing this changes is where or not the dev configurable dismissible notices are seen at least once.

Is there any hope about this?
