Bump a bunch of versions
Bump a bunch of versions

Bump a bunch of things to the latest versions. In particular, make sure
that assertj, jackson, log4j, and slf4j are all at there latest
versions. I also checked to make sure junit, dropwizard, and dagger are
all at their most recent versions, so there's nothing to do here.
