Template access to LJ::set_(active|dynamic)_crumb and LJ::need_res

[pauamma]

foxfirefey's let's keel BML ded (and eat its head) nudged me into TTizing the stats pages before they get too unwieldy. So (because that page uses crumbs) I'm looking at how to set a crumb in the template (which I think is the proper place to do it, since templates map better onto pages than controllers do IMO). The interface I'm thinking of (tentatively - I haven't actually tried this yet) is something along the lines of:

(something relying on RAWPERL, which is (and will likely remain) disabled, so filter/plugin it is instead, per exor674's comment below)

I'm also wondering whether to make it a filter (or something) in DW::Routing::Apache2 instead, but I don't want to make further work on it harder if I can avoid it.

Anyone has a thunk about this? (Specifically exor674 and foxfirefey, since they're leads on this, but not limited to them)
