Feature request: @set for other typeclasses

[TehomCD]

Brief summary of issue / Description of requested feature:

Attributes and Tags can exist in other typeclasses beyond PlayerDB and ObjectDB, but can currently only be set with @set on those two typeclasses, with @tag only working on ObjectDB. It would be a nice feature if they supported specifying typeclasses with a switch or some other mechanism.

Steps to reproduce the issue / Reasons for adding feature:

1. Allow @set/@tag to be more general purpose tools

Error output / Expected result of feature

Extending functionality for @set/@tag

Extra information, such as Evennia revision/repo/branch, operating system and ideas for how to solve / implement:

Maybe something like checking if any of a command's switches are in a command's valid_typeclasses, where the 'valid_typeclasses' property is a set of the allowed typeclasses for a given command, and if so, calling that typeclass's search method rather than object_search. Since they all have tag/attribute handlers, all that really needs changed is fetching them, everything else should work identically.

It might be good to be able to close this by adding the same functionality to the tag command as well. A PR anyone?
