Changing badge title does not update the badge slug

[lmorchard]

I changed the title to a bug, but the slug remained the same. The slug should change.

Hmm, actually I wonder if I did this on purpose: The code only sets a slug the first time, and I might have done it that way so that renaming a badge doesn't break existing links to awards and things.

Oh, this is trickier than I thought: I didn't want to rigidly tie slug to title, because programmatically created badges need more freedom in using slugs as IDs. Need to revert this "fix"
