Added Ecent Handler Mapper

Polling Station Dashboard have a lot of logics extend or close some
pannels (Settings and the Status log), search for users, and eddit those
users.
In order to simplfy the logic of Polling Station Dashboard Controler this
class was invented, the idea behind is simple every time some event is
trigered we will activate the apropriate handle method of the apropriate
object, this way if tomorow for say i want to implement different search
algoritm of users i will only change the UserSearch part.
