[BioC] how often are annotation packages updated (with respect to hgu133a.db and hgu133plus2.db)

[Marc Carlson]

Hi Andrew,

The annotation packages are all updated every 6 months and hgu133a.db is
no exception.  However, after looking at this very closely I have decided to
rebuild hgu133a.db.  A new version of this package will be online very shortly 
and will only be slightly different.  But the small issue you discovered will be gone.
