More helpful errors (in lieu of an actual debugger)

[splinter]

Errors like: “tables.TableError: No such column ‘…’ in this table” would be much more helpful if all known details were communicated. Which table is “this table”? When I can clearly look at the table I think is in question, and see the column is there, this error is slightly infuriating…

Step through debugging would definitely be huge.
