One thing on this: what order should we use when applying filters from
different groups. You can see with RT scrips how much situations could
be when you want predefined execution order. If I want set filter by
content(regexp) on the column then I don't want some global utf8
filter to drop utf8 flag before content filter. Or if I have truncate
as type specific filter and also validate emails with column filter,
then I don't want run truncate after email validation, but before. So
order should be configurable or at least strictly defined with one or
two rules.

Also Filters have no access to all context now: no acces to the record
and no acces to the handle.
