rB8b7cd1ed2a17 broke this for the paint slots
rB4669178fc378 broke this for regular attributes
Name filtering in UI Lists works when:
- [one] the items to be filtered have a name property
-- see how `uilist_filter_items_default` gets the `namebuf`
- [two] custom python filter functions (`filter_items`) implement it
themselves
-- if you use `filter_items` and dont do name filtering there, the default
name filtering wont be used
So, two problems with rB8b7cd1ed2a17:
- [1] items to be listed changed from `texture_paint_images` to
`texture_paint_slots`
-- the former has name_property defined, the later lacks this
- [2] the new `ColorAttributesListBase` defined a `filter_items` function,
but did not implement name filtering
And the problem with rB4669178fc378:
- it added `filter_items` functions, but did not implement name filtering.
These are all corrected now.
