As suggested by Ryan and OtherBill, change the way that

mod_charset_lite checks to see if its filter will be
added by another module.  Now, we run our insert-filter
hook really last and look at the actual filter chain.

(Note that http runs even later but it doesn't currently
do anything which would interfere.)
