6597d789b7 Avoid slice out-of-bounds indexing panic.
The gettransaction handler was attempting to lookup the "sent-to"
address of an outgoing transaction from the transaction store (as a
wallet credit).  This is the incorrect address when sending to an
address controlled by another wallet, and panics when there are no
credits (for example, sending to another wallet without any change
address).  Instead, use the first non-change output address is used as
the address of the "send" result.

This fixes the panic reported when debugging issue #91.

While here, fix the category strings used for wallet credits to
support immature and generate (the categories for coinbase outputs).

242cb22719 Check every error.
This change is the result of using the errcheck tool
(https://github.com/kisielk/errcheck) to find all unchecked errors,
both unassigned and those assigned to the blank identifier.

Every returned error is now handled in some manner.  These include:

  - Logging errors that would otherwise be missed
  - Returning errors to the caller for further processing
  - Checking error values to determine what to do next
  - Panicking for truely exceptional "impossible" errors

On the subject of panics, they are a sharp tool and should be used
sparingly.  That being said, I have added them to check errors that
were previously explicitly ignored, because they were expected to
always return without failure.  This could be due to fake error paths
(i.e. writing to a bytes.Buffer panics for OOM and should never return
an error) or previous logic asserts that an error case is impossible.
Rather than leaving these unhandled and letting code fail later,
either with incorrect results or a nil pointer dereference, it now
produces a stack trace at the error emit site, which I find far more
useful when debugging.

While here, a bunch of dead code was removed, including code to move
pre-0.1.1 uxto and transaction history account files to the new
directory (as they would be unreadable anyways) and a big chunk of
commented out rpcclient code.

c3224f4fbc Begin update to use btcnet.Params.
This is an intial pass at converting the btcwallet and deps codebases
to pass a network by their parameters, rather than by a magic number
to identify the network.  The parameters in params.go have been
updated to embed a *btcnet.Params, and all previous uses of cfg.Net()
have been replaced with activeNet.{Params,Net} (where activeNet is
the global var for the active network).

Although dependancy packages have not yet been updated from using
btcwire.BitcoinNet to btcnet.Params, the parameters are now accessible
at all callsites, and individual packages can be updated to use btcnet
without requiring updates in each external btc* package at once.

While here, the exported API for btcwallet internal library packages
(txstore and wallet) have been updated to pass full network parameters
rather than the btcwire definition of a network.

f36a83b3cc Rename tx package to txstore.
Prodded by @davecgh, and I had this change in the back of my head for
a while now anyways.
