Main Changes:

1) Change the Code to compile with SBT 0.13  ( it was unable to compile under SBT .13 due to the Test-Interface changes)
2) Replace the org.scalatools.testing  test-interface with new sbt.testing interface
3) changed the hard-coded "0.0" test time on "testcase" with newly added sbt.testing.Event.duration() method, now the testcase element is reporting run time in milliseconds
4) change the build.sbt version to 0.4.1-SNAPSHOT
5) add sbt-idea plugin in the project
Merge pull request #5 from chesterxgchen/master

fix broken build for SBT 0.13 and support new sbt.testing test-interface
Delete plugins.sbt

deleted plugin definition for intellij, as IDE plugins should not be part of the plugin definition for an individual project but rather definied globally by each user (everybody has a different idea about their individual favorite editor/ide)
