rewrite client in EmberJS

Starting to rewrite client in EmberJS.
Main features, which are not implemented yet:
* api.php is not compatible with Ember Data yet. Data is stored in Locale Storage of the browser in this stage of development.
* Encryption / decryption of data is not implemented yet.
* There is an error on loading stored data due to embedded objects. Working on a fix, but loading a saved poll is not working for this reason yet.
* Adding user to a poll is not implemented yet.
* Any features for user interface like datepicker are not implemented yet.

To  test application you have to open #/create in browser. A route for index is not defined yet.
Implemented a simple server-side api to store data
fixing transitionToRoute error after saving poll
adding id to response of read data as a work-a-round, have to find a nother solution as pushing id to the data will not work with encrypted json
adding update mode
assign new user to poll
There seems to be an error in ember data with mixed use of embedded and non-embedded hasMany relationships; users relationship in poll is not saved, when it is not embedded (should save the ids)
forgot to commit ember-1.2.0.js
