[split] Teemu's Part Checker

[Chris Dee]

yes please.

we have brought the BFC-problematic files to nearly 0 now.

just a small handful of "weird relicts" are remaining:
https://www.ldraw.org/cgi-bin/ptbfcstatus.cgi

I suggest to delete all of them from the PT:
- one is a "minifig torso + head" physical shortcut assembly which - if we would add these combinations to the library - would make the library size explode due to the possible combination
- the others are mockups which have no visual resemblence with the parts they mimick and are waiting unfinished for years now on the PT.

All now deleted.
