Column Grid / Single Listing Template Alternative

[niccol]

I re-worked the Single Listing Template mod for Zen 1.5

Part of this was just because I struggled to make the further adaptations I needed on that existing code. I just wanted it to work the way that I needed and it is no criticism of SLT in the slightest.

Mine is called SNAF because I tried to arrange the letters 'S' 'N' 'A' and 'F' (specials, featured, all, new) and this arrangement made me laugh.

What it does:
-- adds column grid functionality
-- installs nicely in 1.5.0
-- let's the user choose to use product_listing format rather than default format for specials, new, featured, and all listing from settings in admin
-- adds a dropdown filter to product_listing in column view so the listing can be sorted according to criteria such as price. Display of this is set in admin for each listing individually
-- let's the user choose to include salemaker items in specials or not
-- adds the ability to use get parameters on the specials page to filter by category so that it is easy to create specials pages for a specific category

What it doesn't do :
-- play well with previous versions without modifying the sql statements. basically it auto-installs the sql stuff to suit the structure needed in 1.5. Re-working it for previous versions would be possible but let's move forward.
-- do anything at all with the center boxes like SLT does. It just works with the main listing pages

SNAF unashamedly does the things that I need it to do. But if anybody would like to try it on 1.5 and attempt to break it and spot my typos and errors I would love that. Please let me know how you get on.
