Remove dangling dependencies on tools.logger

Merge pull request #22 from shopsmart/err-to-warn

Fix dangling test dependencies; add codox.

Remove logger dependency

• With the upgrade to log4j2/slf4j upstream, having a logging dependency here can mess up downstream projects. Instead, we define a metalogger in clj-foundation.errors that logs to out and err by default and can be replaced to forward anywhere.

Readable stack traces in log; added dependency on io.avisio/pretty

• Readable stack traces in log; added dependency on io.avisio/pretty
• Removed log4j config file that broke some clients

Log retries as warnings, not errors

• We decided that the library shouldn't be opinionated that retries are errors and lowered their log level to warning.

Minor feature enhancements

• Rethrow the actual exception after retry hits max-retries or abort-fn returns true
• errors/<-seq can now unwrap java.sql.SQLException too

Fix bug in errors/retry-with-timeout

• Purely a bugfix release

Always schema/validate retry-with-timeout

• No new functionality; retry-with-timeout now throws aggressively if passed bad data.

Bug fix release to io.clj - resolves resources correctly
