Prestashop customizations

here is a list of what needs to be done:

- product list, need to order by availability

- moving elements on product page:
1) https://prnt.sc/1190dn8
2) http://prntscr.com/11hfz8u
3) http://prntscr.com/11fy9jj
4) https://prnt.sc/1qh0cuz

- missing info on smartphone view

- icecat module
we have a custom plugin, a connector Icecat. It's required an extra table for the groups and then the info displayed in the product page, grouped according to this table

- "configuratore" more than one category in the filter

-------------------------------------

**VERY IMPORTANT**

-ONLY ACTUAL DEVELOPERS ARE WELCOME. NO REBIDDERS
-Money released only when the job is completely done
-we have a test site for devs, once everything work, the job is moved to the production site for the final test
-no PS or Theme core files can be touched, everything needs to be done in override/hooks
soon we will update both and if core files are touched then we would lose everything
