fix: don't crash/terminate upon errors within chokidar

DanTup · DanTup · commit 2c389311ce68 · 2014-04-12T13:30:47.000+01:00
Handle errors from chokidar and route them to the console. Previously, these unhandled errors (which are very common when editing in Visual Studio) would cause karma to terminate and all browsers to vanish. Fixes #959
