Easy to install.

!!!!! Backup your catalog/includes/column_left.php first!!!!!
!!!!! (or if categorie box is on the right site the column_right.php) !!!!!


!!!!! Installation on your own risk. !!!!!

credits goes to prior developer, who made this great contrib!

I'll read somewwhere, that user want to categories opend till categorie x, so added this to this contrib.

added features:
- Option: just open the first 'n' categories till level 'x' and the rest till level 'y'
- Option: additional layout
- Option: if user is in categorietree, close the other catgories till level 'z'

Features:
- little image in front of categories, depending on categorie has sub's or not
- show categories and subcategories till defined categorie level
OR show all categories and all sub level
- don't show empty categories or show

This contrib adjustment was made, because I can't have all categories with ALL sublevel opened, it's to much,
but I want to have them opened till Level 1.
