load_procs should warn rather than erroring if a proc with a duplicate name is loaded

[FishmanL]

in particular my blueprint registration is idempotent in other ways, so it might be getting run twice -- any chance of a silent failure on load_procs?

I guess I'd probably be fine with a warning instead of an error. If I were looking at your code, I'd probably want to figure out why I need to register the procs multiple times, though. That seems less than ideal.

A pull request would be welcome. I'm unlikely to write this up myself.

Done! (The short answer for idempotency is 'our blueprint registration is complicated and multipathed, and somewhere in there is a small bug that I do want to fix eventually')
