Update TernJS Lib to fix Angular crashing ST

I recently started an AngularJS project and with sublime-tern enabled the editor would hang and freeze whenever I went to edit a JS file in the project. After coming across [angular.js file causes tern to hang/crash](https://github.com/marijnh/tern/issues/142) I tried updating the plugin to the latest ternjs core and it alleviated the editor crashing. I realize you'd probably update the ternjs version in the plugin sometime soon anyways but I figured I'd submit a pull request anyways since I was trying to fix this particular problem I was having. 

Thanks for the great plugin.
