Bulk generate ignores new feed settings

I've made a patch that takes a rather timid/conservative approach but seems to do the job. In taxonomy_pathauto_bulkupdate, it was checking whether the taxonomy term existed, and if not it called _taxonomy_pathauto_alias to create the taxonomy alias and, if requested, the feed alias as well. I added a condition to call _taxonomy_pathauto_alias if the feed alias does not exist. I also noticed that the count of how many aliases were created is off, since it doesn't count the taxonomy aliases and the taxonomy feed aliases separately, but I made no attempt to fix it.

A more aggressive solution might be to divide the _taxonomy_pathauto_alias function to handle creating the two types of aliases separately. This could fix the count issue too.
