aiorpcx 0.20 changed the behaviour/API of TaskGroups.
When used as a context manager, TaskGroups no longer propagate
exceptions raised by their tasks. Instead, the calling code has
to explicitly check the results of tasks and decide whether to re-raise
any exceptions.
This is a significant change, and so this commit introduces "OldTaskGroup",
which should behave as the TaskGroup class of old aiorpcx. All existing
usages of TaskGroup are replaced with OldTaskGroup.

Previously if the user disabled FX rates in the settings, the UI
would keep showing the fiat amounts everywhere until the next time
the program was started. (and the rates would not even refresh anymore)
Added Brazilian Bitcoin Index from Cointrader Monitor (https://cointradermonitor.com/api/pbb/v1/ticker) as a "BRL" Fiat source.
The index is calculated from the last price and volume from 30 brazilian exchanges. It is a well-known price index used by bitcoin brazilian users.

In kivy, if the user enabled fx rates but did not touch the fx history settings,
the GUI would show that history rates are enabled but in fact they would be disabled:
the GUI called fx.get_history_config(default=True) when displaying the checkbox,
but exchange_rate.py would not fetch history rates.
(it would only get fixed if the user touched the fx history checkbox)
Note: FxThread.run() calls fx.show_history(), which calls fx.get_history_config() without arguments.
and if they had already been saved, treat them as if nothing was saved
context: BitcoinAverage started restricting the historical API endpoints.
they now deny unauthenticated requests. :/
- BitcoinAverage seems to have historical rates for all currencies it supports
(as in, if there is spot price, there is also history).
- BitStamp now uses v2 API, also has support for EUR.
- Bitcointoyou does not seem to actually offer histories
(and `request_history` was undefined anyway)
- regenerate currencies.json
