fix bug: if the project which is opened during opening IntelliJ has not included junit lib, fireworks can't be installed.(Thank johnny.pu for reporting the bug).
I still have no idea about how to handle project without JUnit lib included, so I just always return false when identify a JUnit TestCase.

For I can't update plugin in the plugin repository now, please download new version from:?http://dontmakemetest.googlecode.com/svn/trunk/dist/fireworks.zip
Any feedback is very much appreciated.
