autoWatch for symlinked folders not working

[JauernigIT]

We want to use Karma in a "continuous testing" setup with singleRun: false and autoWatch: true (run as Gulp task). The tests run fine initially and on file changes. Unfortunately, this isn't true for symlinked folders. If we change a file in a folder that is symlinked to a subfolder in the Karma basePath, the watcher is not recognizing it.

Environment: Windows 2008 R2, Karma 0.13.21, Gulp 3.9.1
