gam: update to 7.00.39

This package was previously Jay Lee's Legacy GAM.

GAM 7 is a merge-back of Ross Scrogg's GAMADV-XTD3 branch which is a
rewrite/extension of Legacy GAM so that is only one project going forward.
As such, it is not possible to provide a clear list of changes from the
final version of Legacy GAM.
