[LSC Request] End of header meta command

[Santeri Piippo]

Allen> A "needs work" tag is useful as machine-readable as it allows tools e.g. LDFind, to easily point out that a part could do with some touching up. Thus part authors can get a list of parts that they might improve.

I could implement support for this in LDForge if it is ratified. I also would find the end-of-header meta command particularly useful. I think "////" sounds a little ambigous and unclear though. I'd prefer "0 !END_OF_HEADER" or something like that.
