[Bioperl-l] NCBI Blast via HTTP

I have a tentative fix for this which I've committed to CVS.  When  
Jason set up the module he checked for the xml header tag as well as  
the status line but had no specific check for text/tabular output.  I  
added a check for the first BLAST line which should break out of the  
loop for all BLAST types (famous last words...) which passes our tests.
