Feature/timeline crud

Implemented adding new events to the timeline.

Some UI thinkg are still missing, like disabling "addEvent" button before dataSet is loaded etc.

First I would like to modularize everything: separate eventLoadingForm, newEventForm or something like this.

Please don't merge until not finished by me :P
in this case it is cool, because you are using this container only once! 
but if you want to use some variable more than once and perform some jQuery operations on it prefer convention for using jQuery objects like this:
var $container = $('#container'); 
$container.someAction();

and when you want to have clear DOM element then do just $container.get(0)
