Please remove dist files from PR :D

Done.

@asleepwalker can you update the wiki please?

@user378230 of course, but where I should write about it? This pull request was not about adding callbacks like existing onSelect and onRemove, but only broadcasting an event.

There are similar scope events here:
https://github.com/angular-ui/ui-select/blob/master/src/uiSelectController.js#L114
https://github.com/angular-ui/ui-select/blob/master/src/uiSelectController.js#L391
https://github.com/angular-ui/ui-select/blob/master/src/uiSelectController.js#L420
and they are not documented in the wiki.

@asleepwalker A sorry I saw the Events heading a thought they were scope events.

Feel free to add a section Scope Events to the ui select wiki page (the one I linked previously).
