Stop relying on currency.hardcoded.net

I don't want to have to maintain that server forever. We can query the Bank of Canada and Yahoo directly from moneyGuru.

Is it possible to post the server code in a separate repo for analysis and for posterity's sake? I know that is probably still proprietary, and probably isn't too complicated just some XML RPCs right? But would be interesting to see. I haven't looked at that portion too closely.

Alright, let's do this (after #429). The task is rather simple: take the fetch_boc_rates unit from the currency server and implement it as a moneyguru plugin.

Oh, I see that the link I gave earlier is now a 404. Sorry about that, I think I mistakenly erased it recently. I'll git-ify it and push it on github.

As a bonus, I think I'll improve the "Currency Rates" plugin to include the last fetch date so we can more easily debug currency fetching.
