ANN: TestNG for IntelliJ IDEA integration 0.1.0

TestNG integration is now available in the plugin manager for your
testing love....

You can find it under "Tool Integration" with the name "TestNG-J".
Moments after the upload we decided to drop the -J as it sounds tacky,
but we'll get to that on another build.

Things to note:

- This plugin is compiled with JDK 1.5 ONLY
- This plugin includes TestNG 2.4.2 for JDK 1.5 ONLY

Sorry to any 1.4 TestNG users out there...

Many thanks to Hani for the much needed contributions to the plugin.
