Added separation of flags according to ordering

Summary:
Refs T2841 - Exactly what it says on the tin

Turned some ordering around.

- Color is `ASC` to be in line with the flag dialog
- Object type is `DESC`, since `TASK` and `DREV` are sure more of
interest than `CMIT`

NOTE: May not work properly without D5514, since only a few
object handle types implement `getTypeName()` properly. The fallback
return value is `null`, after which we group when sorting per object
type. Dis gun b gud!

NOTE…
