This took longer than I expected, but its done now.

There is a new file Bio/GenBank/Scanner.py which includes a base "INSDC 
scanner" which handles the common code (e.g. feature tables) with two 
subclasses, a GenBankScanner and an EmblScanner.

I have updated Bio/GenBank/__init_.py to remove my old Genbank only 
scanner, and call the new GenBankScanner instead.

I have also updated Bio.SeqIO to use this new code for both GenBank and 
EMBL formats.


Note: The handling of newlines and white spaces has changed slightly as 
a result of these changes.  I updated the expected output for the 
test_GenBank unit test  Incidentally I think this "fixes" Bug 1981:


Other than that, touch wood, nothing should have changed for GenBank 
users.  The relevant unit tests look fine.

The EMBL support has a few bits that need polishing (search for TODO in 
Bio/GenBank/Scanner.py for points that I noted at the time), and some 
rigorous testing of course.

I should probably add some EMBL examples to the SeqIO unit test...
