When product is installed but disabled, show the analytics viewlet normally.

This fixes issue #5.

When the cookiecuttr product is installed but disabled, the current master and the latest release does not show the analytics viewlet. There are even tests that check this, so maybe this is actually wanted, but I do not agree and it looks like @richardtc does not agree either in issue #5.

I think that the product should show the analytics viewlet normally. Alternatively, you could of course uninstall the product, but then I wonder what the goal of the `activate` checkbox is.  It claims to activate the cookie cutter, but when disabled it effectively disables the analytics viewlet.

It has some minor package cleanup as well, but if that is too much, you could cherry-pick commit 02a87f54555a195354f3e8028040b3741a05e32c as this has the real change.
