[Typo3-shop] Avoid extension chaos please

I have used the latest tt_products from Typo3.7 and updated it now. Here 
are the sources:
http://fholzinger.com/typo3/typo3/ext/tt_products/pi/
I have changed only class.tx_ttproducts.php.
You can test it if you want. No orders will come from this test site. 
But do not use the Paypal Button please.
The bill will look like

The order tracking:

So I will make the project leader now for tt_products. Or has someone 
else wanted to do this job?

tt_shop

I have one shop to test. But it would be better, if also others test it 
with their shops.

I am now not quite sure how I can program CONSTANTS, so I have always 
used only SETUP variables.
I can access this via $this->conf["outputFolder"] only when I have 
written it into the SETUP field and not from the CONSTANTS field of the 
template.

How do I get the documentation source for tt_products so I can extend 
it? - only using the SWX file?

What are the next steps that this will come into Typo3.8?

I think it is better if I finish this first. Later I will continue with 
bringing in the next tt_products derivates.
