Revision 499486

A (large) patch from Scott Gray  "Update ASL header" (https://issues.apache.org/jira/browse/OFBIZ-637).
I put also some svn:ignore for shark build and lib diretories and assetmaint/build 

I did some by hand lately, too much to remember. They were files with old header but without copyright. A 1st attempt I suppose, will have to check this after this commit.

I add some problems to commit this patch in one piece because it's so huge (specially with Eclipse I had to turn to Tortoise) !
