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
http://localhost:9000/upload  => @baseUrl + 'upload' 

but you moved it to seperate module. We need to create some global settings object to handle such situations to not hardcode links etc. I will do that in mean while ;) Don`t worry
