Add more Events

[Jupi007]

Q	A
Bug?	no
New Feature?	yes
Community Bundle Version	2.0
Sulu Version	2.5

Actual Behavior

I currently try to use this bundle into a personal project, and I need to listen some community related event to execute related actions in my code. But some actions do not send an event when executed, such as email confirmation.

Expected Behavior

Each actions from this bundle should dispatch at least an event when performing.
By the way, ideally there should be some pre/post events so we can extend this bundle.
