Fix Javascript error on Create Poll click from Event create/update

* Remove leanModel call on #new-event Dom object that was not necessary
* I am not sure why this was here originally. The button currently does not launch a model it is just a link to another page. All tests pass after removal.
* Because of the indention correction it's not obvious where this was done. See line 19 of jquery.app.js file.
* Remove redundant $(document).ready call from jquery.app.js
* Beautified jquery.lean-model.js file for easier debugging. This is a non-issue since asset pipeline will uglify upon deployment.
