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).
