Spring cleaning for some of our APIs

Of note, the Wave API is getting tossed out. Final nail in the coffin, I suppose.

I hope translate may be reconsidered. It's made navigating the worldwide web -- without shoving everything through the Translate web page interface -- more than just more convenient; it's made doing so possible/practical, for the first time.

I think this may be an instance of "baby with the bathwater". (In other words, there's a cultural mission/service here that deserved continued support, even if it takes some more neurons devoted to beating the abuse.)
