BCH cashaddr: full support

- BCH addresses are now displayed in cashaddr format by default.  This may be
  overridden on the command line with --cashaddr=0, or in the config file by
  setting `bch_cashaddr` to false
- In tracking wallet views, the ‘h’ key toggles between legacy and cashaddr
  address display
- Transaction views display BCH addresses in both formats simultaneously
- The --usecashaddr=0 daemon option is no longer required and should be omitted

Testing:

    $ test/unit_tests.py -v cashaddr bip_hd.multicoin
    $ test/gentest.py --coin=bch -v --type=C 1 test/ref/bitcoin_cash/bchwallet.dump
    $ test/cmdtest.py -e bch_txview_cashaddr1 bch_txview_cashaddr2
    $ test/cmdtest.py --coin=bch -e txsend regtest.view autosign_automount
    $ test/cmdtest.py --coin=bch -n ref3_addr
