Title: Process sff

Added is_gzip function to qiime.util, which checks the first two bytes of the input file to see if they're 1f8b (magic number of a gzip). Modified qiime_open to use this function. Modified process_sff and test_process_sff so that the function now raises a TypeError if the user tries to process a gzipped SFF file with sfftools.
