Change to WGA2GenesDirect.pm and BaseGeneBuild.pm
For WGA2GenesDirect.pm pass in undef instead of empty string when creating the QUERY_DB database adaptor.
For BaseGeneBuild.pm, in the case of a non-standard dba being passed into get_dbadaptor it previously searched
for some information about the adapator requires, e.g. matching on 'compara' or 'functgen'. But if none of
these cases were matched it would just continue on without assigning anything. Put in an else in this case
which is just a throw
Change to BaseGeneBuild.pm
Update the text on the throw to point out that undef should be passed in for a
standard adaptor
Change to BaseGeneBuild.pm
Now with spelling
