Customizable drawers

Updated version here: https://www.thingiverse.com/thing:3181631

This is my contribution to cruzher organizer.

I remixed costmo and CNCer projects to give more flexibility, this can resume many of other remixes.

- costmo derived project can have or not nameplates and can have different compartments and finally doesn't require anymore any .stl file to reside in same directory

- CNCer derived project add double height and fix some "irregular" quotes.

for lazy people I've added some items

Shelf:
- isTopCover = true: creates only top cover
- isBottomShelf = true: create shelf with bottom cover
- moduleHeight = 1: standard drawer height
- moduleHeight = 2: double drawer height


Drawer:
User should modify only 'compartments', 'moduleHeight' and 'hasNameplates' variables

- compartments = [1]: 1 compartment drawer
- compartments = [1, 1, 1, 1, 1, 1]: original costmo drawer
- compartments = [3, 3]: 3x2 drawer
any other composition is allowed

- moduleHeight = 1
