[Xotcl] Collections

This is an item for the suggestion box.

XOTcl uses a number of collections: filters, mixins, children, etc. It may
perhaps make sense to introduce a real collection class or abstraction,
and implement those concepts directly *as* collections. Reading through a
lot of XOTcl code--eg, xoRBAC--you can see that the same themes appear
over and over again, such as checking to see if an object is already mixed
in. Right now "append"--and only "append"--is built into the list of
supplied Object methods (eg, "filterappend"). Rather than flooding Object
with more and more collection management procs it might be better to
expose the filter collection as an object that supports operations
directly (like "append" and "contains" and "remove").

This is more like a 2.0 change--and presupposes that there will be a 2.0.
