Better error reporting

[lukechilds]

We are limited to what we can do at the moment because marketmaker is inconsistent with how it reports errors and when when it does report error we very rarely get an error code to reference.

But we should do as much as we can to make the errors clearer wherever possible.

We're waiting on documentation for failed swap error codes: https://docs.google.com/spreadsheets/d/1blgmrJCZ-SfYaJdTTVdk717kZ43R4yzm9YIW2Bt--EM/edit#gid=0

Error reporting could be improved quite a bit with all the JSON responses that mm2.0 now returns. See the API
