LDCad shadow library github repository

[Max Murtazin]

I've made some changes to the (currently dev version only) shadow validator inside LDCad.

It now forces this:

Code:

0 LDCad shadow info for "Stud"
0 Author: LDCad Shadow Library
0 !LICENSE CC-BY-SA 4.0, see LICENSE.md
0 !HISTORY 2022-07-23 {Roland Melkert} Initial info for stud.dat

0 !LDCAD SNAP_CYL [ID=studC] [gender=M] [caps=one] [secs=R 6 4]

Still not sure about the author line though.

And maybe add an empty line before the history (like LDraw part headers).

I also would like a 'real' first info date. But most of the files have a creation date of 2020-04-06 because that's when I copied the 1.7 branch from 1.6

Does LDCad even require an author line? If not, just no reason to keep it at all then
