This adds an additional config option, -cafile, to specify the root
certificates checked when verifying a btcd TLC connection. btcd will
now automatically generate certs in
~/.btcd/data/{main,test}net/rpc.cert, and this file should be copied
to ~/.btcwallet/cert.pem.
The -btcdport option is also gone now, and replaced with -connect (or
-c), to specify both the hostname/ip and port of the server running
btcd.
To start btcd and btcwallet with all the right settings for testnet,
the Btcd Suite batch file should be run from the start menu rather
than btcd and btcwallet individually. Update the README to reflect
that.
