[LSC] File Format Restrictions for Official Parts

[Michael Heidemann]

Pov-Ray statements are not allowed (http://news.lugnet.com/cad/?n=11706).
I think the old files doesn't matter at this point. This document should 
lead the way into the future. As I do not want to have a long period 
where nothing happen on the pt I think we should leave them or fix them. 
But for new part submissions from the date of releasing this document it 
should be restricted.
