Customizable Peg Board Hook - with connected hooks support

From original:
!!! WARNING !!! THE CUSTOMIZER DOESN'T GENERATE VALID .STL FILES AT THE MOMENT AND THIS ONLY WORKS PROPERLY IN 2016 OR NEWER VERSIONS OF OpenSCAD.

This is a customizable peg board hook. You can alter different characteristics about it to suit your needs. It supports both Type A and Type B peg boards.

Modifications:
This has more settings and supports generating multiple connected hooks ( I needed it to help hold together Modular Peg Board
from https://www.thingiverse.com/thing:4024310 , probably incorrectly installed and later my remix : https://www.thingiverse.com/thing:4692407 ).

Thingiverse customizer is usable for preview only and doesn't show a proper one by default - change ( and optionally revert ) any setting to fix its preview.
