Introduces WalletService object which is in control of
blockchain and wallet access.
The service manages a single transaction monitoring loop,
instead of multiple, and allows updates to the wallet from
external sources to be handled in real time, so that both Qt
and other apps (yg) can respond to deposits or withdrawals
automatically.
The refactoring also controls access to both wallet and
blockchain so that client apps (Taker, Maker) will not need
to be changed for future new versions e.g. client-side filtering.
Also updates and improves Wallet Tab behaviour in Qt (memory
of expansion state).
Additionally, blockchain sync is now --fast by default, with
the former default of detailed sync being renamed --recoversync.
This refactors YieldGeneratorBasic a bit. In particular, we move things
that custom algorithms will most likely want to change to separate
functions. That way, it is easy to define the behaviour of inputs
and outputs for the join without the need to duplicate the other, more
general logic of create_my_orders and oid_to_order.
Previous to this commit, the jmbitcoin package was accessed via
a file in jmclient `btc.py` which was originally added as an
interface to allow the client to use a non-jmbitcoin package to
provide the implementation; while this idea is useful, the way
it was implemented was not, moreover it is not currently used
and contained duplicated code that was unmanaged. Also, the
original usage of this was only by the electrum plugin, which
has currently been abandoned. This simplifies the code and
avoids spurious error messages. Note that most of the changes
are a result of pulling the logging function directly from the
jmbase package instead of indirectly via this interface (which
was unnecessary and not connected with jmbitcoin).
