[antlr-interest] ANTLR 3.1, headers in imported grammars

[Terence Parr]

added bug to fix for 3.1

http://www.antlr.org:8888/browse/ANTLR-301

Actually, wait.  So we are saying that the header in root grammar  
should override any in subgrammars?  In this case, there are none so  
it inserts it?  That will be special case.  @members are not  
overridden for example.
