Upgraded asynchbase to 1.4.0
Remove asynchbase dependency overrides

I don't believe these are still required, and it looks like they're
causing more trouble than they're worth as they require manual updates
every time the dependency on `asynchbase` has its version bumped.

Refs #2
updates to support dropwizard 0.6.0-SNAPSHOT changes
Fix dropwizard-extra-scala for 0.6.0

  * Renamed `com.datasift.dropwizard.db` to
    `com.datasift.dropwizard.jdbi`.
  * Renamed `Database` and `DatabaseWrapper` to `DBI` and `DBIWrapper`
    respectively.
  * Removed `GraphiteReporting` trait for bundle mix-in. Directly add
    the `GraphiteReportingBundle` to your `Service` using:
    `Bootstrap#addBundle()` instead.
