Changes between 2.0.4 and 2.0.5

swap-tx! now uses transact-async instead of transact so that it is not subject to transaction timeouts.

Added a new core/create-database-with-retries fn that is used by core/initialize to more reliably create databases. Often this is the first thing you attempt to do on application startup and if you just started your Datomic transactor as well (e.g. in a scripted dev environment), there can be a race condition where this code attempts to create the database too early and datomic.api/create-database throws an exception. This catches those exceptions a few times, tries again with increasingly long delays, and eventually gives up and re-throws the final exception if it doesn't succeed.

Added support for a :migration-tx-instant optional config param that can be set to a java.util.Date value. This will be used to set the :db/txInstant of the schema migrations when present. Higher arities of the relevant migration functions were also added to facilitate this (but the old ones were kept too so this should not break existing code).

Updated dependencies, which shouldn't affect users much since you should be using your own Clojure, Datomic peer lib, etc.

Moved default Datomic connection into an atom because we discovered that datomic.api/connect sometimes has long (5+ second) pauses even though its docs say that it caches connections and is safe to call repeatedly. This was true in Datomic 0.9.5327, anyway. We're working with Cognitect to figure out if this is a bug, but this seems like an OK way to do things either way.

Removed turbovote/resource-config dependency. Now you should pass in your config to datomic-toolbox.core/initialize or datomic-toolbox.core/configure! before using any of the zero-arity stateful fns (see list below). This is a breaking change.
Made the following zero-arity functions optionally take connections and/or database args in addition to working with the defaults setup by initialize or configure:
- applied-migrations
  - zero-arity uses (db)
  - single-arity takes Datomic db value arg
- unapplied-migrations
  - zero-arity uses (db)
  - single-arity takes Datomic db value arg
- run-migration
  - single-arity takes migration EDN file arg
  - double-artiy takes Datomic connection and migration EDN file args
- run-migrations
  - zero-arity uses (connection)
  - (there is no single-arity version)
  - double-arity takes Datomic connection and Datomic db value as args
- install-migration-schema
  - zero-arity uses (connection)
  - single-arity takes Datomic connection arg
- All other functions without higher arities for connections and db values were intentionally left alone because datomic.api already provides the equivalent function (e.g. datomic-toolbox.core/db versus datomic.api/db).

Added a core namespace. Code using this library will need to update require and use statements to refer to datomic-toolbox.core. This is a breaking change.
Updated to Clojure 1.7.0.
Updated to turbovote.resource-config 0.2.0. If you use both this and resource-config, then this is a breaking change for you. You will need to update to resource-config 0.2.0+ as well.
