This commit fixes a bug introduced within a prior commit. The prior
commit failed to drollery reverse the txid string taken in as user
input, therefore in order to properly close a channel, the user needed
to manually reverse the txid themselves.
With this change, `wire.NewShaHashFromStr` is used which properly
reverses the string within the constructor. This allows the string
reported not be directly used to the close an active channel.
This commit also corrects a few logging messages.
Currently positional arguments *are not* supported, and all arguments
must be passed via unix-style command line arguments.
In a later commit support for concurrent positional, and manually
specified arguments will be added.
To try uspv, do ./lnd -spv
The remote node is hardcoded in shell.go. If you aren't
running a full node on localhost, specify where to connect to.
Nearby nodes will be much faster but random testnet nodes on the
internet should also work.
