Enable the <Filter> tag to work with loops

[GabrielGallagher]

Currently, the tag only works within the context of a table.
It filters results dynamically, without triggering a page refresh.
Many users have been asking for the same thing on Loops, and some have expressed confusion at why it works with tables and not loops.

Interesting to see more approaches leveraging the interactivity API for this kind of thing
