Backfill Error Cases for all transaction types

[mDuo13]

Some transaction types have their error cases documented, such as AccountDelete error cases. Other transaction types in the reference don't, and it would be nice to provide that level of detail for all transaction types.

Of course, depending on how complex the transaction type is, it can be pretty difficult to track down all of the possible error codes, which may be buried in different levels or sub-functions of transaction processing. All the more reason that it's worth doing so that users don't have to discover by experimentation what the possible error or make guesses to what they mean.

Also, pay careful attention to the prefix since it's easy to get them mixed up (terNO_RIPPLE vs tecNO_RIPPLE for example).
