WIP: feat-v1-support

[hrgdavor]

Initial implementation of support for V1 scripts.

test url while in progress https://3d.hrg.hr/jscad/v1-support/ or run locally

V1 is not really supported anymore, this is an effort to allow running V1 scripts for many old scripts, but with limited dedication what kind of issues would be fixed. Certainly is very unlikely existing bugs from v1 will be fixed (unless someone is very eager and cotributes a fix)

• [ ] export support (not working yet)
• [x] 2d shapes (outlines, poly)
• [x] colors support (working, but missing default color for partially colored)
• [ ] complex projects with include (may or may not be implemented)
• [x] drag drop .jscad and shim will be added to the script

Bonus over old V1 engine

• correct line numbers for errors reported
• debugger support matching source (jsut write debugger in the script somewhere and if dev console is open it will brak on that line)

colors work and transparency

partially colored objects have hardcoded pink instead of UI default color for now
