Add table exclusion list

[jberkus]

Depends On: #4

Currently we have an inclusion list for databases. It would be good to also have a table exclusion list, which would allow the user to exclude a list of tables which they know are regularly truncated/dropped. There would need to be a seperate list for each mode.

Implemented a while ago; see the built-in documentation on flags --exclude-table and --exclude-table-in-database.
