Using old data for tokens

So I'm still not entirely certain about this one. It appears that when auto_username runs, its token module implementation for the profile module ends up pulling data before changes to the profile are saved. That results in a problem, not just because the data is stale but if the previous data would result in an empty or invalid username, then it becomes impossible to save a user account. Oopsies. :-)

I may just need to increase the module weight so that it runs after profile.module, but I'm not sure. It needs a bit of testing before I confirm that. (Anyone who wants to test it for me and submit a patch is welcome to do so! :-) )
