Bring build toolchain up to current standards

This is a first minimal pass for developing on modern Rubies like 2.2.x:

  - Test::Unit hasn’t been in the standard lib for awhile, switch to
    minitest since it seems to be the preferred community equivalent
    these days versus the test-unit backport.
  - Update mocha for current minutest support.
  - Current Rake versions don’t have RDocTask, so use RDoc::Task and put
    rdoc in the dev dependencies.

-This version is currently based on mongo-1.2+. As there were significant changes
-to the GridFS API prior to v1.0, you may have luck with the git-tagged version
-0.2.0 of this library with earlier versions of the driver.
+The library hasn't been updated for some time and is in the process of being
+brought up to modern standards on the `master` branch. It probably does not yet
+work with current versions of the `mongo` and `bson` gems (patches welcome if
+you need it faster than we can deliver it). Support for Ruby 1.8 is almost
+certainly already dropped on master—it was supported up to gem release/git tag
+v0.4.1.
+
+If for some reason you need support for ancient versions of the `mongo` driver
+prior to v1.2, these were supported in rack-gridfs 0.3.0 and below. 0.4.x
+supports `mongo` 1.2(.x?) which made substantial changes to the earlier GridFS
+API.
