Rounded_polygons are now generated by a function returning a point list.
...
The module version simply passes this to polygon.
The arcs now sections of a circle4n() rather than a circle().

Extension to belt.scad
...
Can now:
- render open loops
- twist the belt
- use pulleys instead of radius in the points list
Fixes some precision a few places
Breaking change in belt_length(); now requires a type argument

Screws.scad is now included in core.scad, so doesn't need to be included

be used internally in the library.
