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
to be honest is(':checked') is the slowest from almost each possibility (whitout checking lenght)
