[IDEA] Second argument to [subfilter[]] to set currentTiddler

[flibbles]

The title says it all. I'm doing some pretty heavy filter work for TW5-Graph stuff, and my filters would be tremendously simpler if I could just set currentTiddler when I invoke the subfilter operator.

Currently, I'm doing stuff like this:

[<someValue>] :map:flat[subfilter<myFilter>]

Which is very suboptimal. :map:flat insists on returning something even if the filter returns nothing, which is an annoying thing to work around. And sometimes I'm finding I need to double-nest :map:flat calls just to get currentTiddler equal to what I need. See the lunacy that my <$nodes.neighbors> macro is becoming.

I'd really love to be able to just do this:

[<someValue>subfilter<myFilter>,<someValue>]

and be done with it. I could make the PR and tests if necessary.

That's interesting. Let's see.
