Subject: cr restyler v2

original made lots of assumptions about the default style (and cr's styles, to some extent)
v2 copies the values from the styles themselves, and only tags if the value is actually different.
works with _all_ styles, not just the 4 i put in v1. still can't help if the cr script doesn't use styles properly.
not quite done yet, still need to sort out the handling of inline tags, but very much usable
