make-initial-stoptags looks for ".ht" extension but load-graph produces ".pt" extension

[chuckpr]

make-stoptags.py is checking for graphbase + '.ht'

infiles = [graphbase + '.ht', graphbase + '.tagset']
    if args.stoptags:
        infiles.append(args.stoptags)
    for _ in infiles:
        check_file_status(_)

...but loading graphbase + 'pt' (and printing ".ht").

print 'loading htable %s.ht' % graphbase
    htable = khmer.load_hashbits(graphbase + '.pt')

Great catch. This is a result of my purge of the word 'hash' from the user documentation. It should be 'pt', for counting hash.

Heh, old habits. 'pt' for presence table.
