bump version - BACKWARDS INCOMPATIBLE CHANGES - see commit message

When upgrading to nodeunit 0.4.0 you'll need to update any testCase's
that use setUp and tearDown to now use a callback on those functions.
See the testCase example in the README.md file for more information.

This now allows the use of async code in your setUp and tearDown
functions.
