The usage of a ripe160 for bitcoin addresses in the API and in the
Indexer loses some info, specifically what kind of script it is.
Additionally not all types of scripts fit this mold. At best that means
its not future-proof.
This adds a method to the API in order to select from a Tx the hashed
outscript (thats singlehashed sha256) and refactor the address indexer
to use that instead of the ripe160 address.
The API enums broke a little, so I used the opportunity to break it a
lot and clean up the enums in order to make them more future-proof.
But, yeah, software from before this commit is protocol incompatible
with software after this commit.
Also upgrade the cashier app with logging, ctrl-c catching
and debug + version command line arguments.
Last, this checks the server version and exits if the Hub
version is too old.
Handle incoming payments, show if under/overpaid and
make sure everything is properly inserted into the database.
This makes the process actually work and useful for a small business
