[LSC Request] End of header meta command

[Travis Cobbs]

I believe that the purpose of the 0 !NEEDSWORK was intended to be as a container for a description of what work is needed. So it would (presumably) be followed by a text description of the work. This wouldn't work with a single meta-command holding multiple flags. Also, "needs work" isn't related to the Part Tracker. It's an acknowledgement that the file has issues, but is still ok for inclusion in the official library once certified.
